Attention Mustang 2005 – up Mustang Owners!
Please Stop and read this 1st!
MAGNUM XL CONVERSIONS IN S197 & S550 MUSTANGS The Bowler All-in-one Harness is not a Plug & Play option. It will require you to terminate wires and add an additional 12 volt key-on ignition circuit.

Please understand that this product does not correct the ratios that you are changing from the Getrag MT82 to the new Tremec Transmission. The Bowler All- in-One product is designed to operate your Reverse Lock-out Solenoid and give the correct Speed Pulse Count for the Speedometer (Period).

• You are required to take your car to a tuner with EFI Live or HP Tuners to change the look up chart in the calibration to ensure that your cruise control works. 2019 – up Mustang owners, This is not recommended for you, due to the transmission conversion you will not be able to use your reverse camera or Rev-Match without additional support from your tuners. However this product will correct your speedometer and control the Reverse Lock-out Solenoid.

If your speedometer works and you can easily shift into Reverse when at a stop, the Bowler All-In-One Harness is working as intended.
You will need to contact your tuner to question cruise control or any other running issues.

Please See page 10 for specific details on installing the Bowler Allin-one into your Mustang.

ALL-IN-ONE WIRING HARNESS SOLUTION

Enclosed is an all in one solution for your Tremec 6-speed Magnum transmission that allows for a simple 4 to 5 wire hook up to give you control over every function included on the transmission.

NOTE If you are using the All-In-One with factory GM speedometer connection or a Magnum XL conversion in a Mustang please read the last 2 pages before completing the installation. The All-In-One utilizes a small, epoxy sealed, control box that will control each of the 3 functions with power and grounding for each function through 1 switched +12v circuit (RED) and 1 (BLACK)wire connected to the negative battery post or engine block. Control of the reverse lockout solenoid is based on a user defined speed setting that is set up through the mobile app. This eliminates the need for a separate lock out control box. The electronic speedometer output connection on the harness is equipped with 2 speed sensor outputs (PURPLE/WHITE & PURPLE/YELLOW); the speed sensor outputs generate a square wave signal that goes from about -5 to roughly +5 volts, varying in frequency as the speed changes. If your ECM needs a positive only input, the output will automatically shift and give you 0 to +10 volts. The 2 speed sensor outputs are completely independent and can be calibrated separately with any pulse count and ratio you want. These two outputs should be able to drive any common speedometer, cruise control, or ECM. If only one output is needed you can choose either wire and cap the other that will not be used. This will give you much greater flexibility in the components you are able to use and requires less time wiring everything up. The reverse lights are powered by a pair of wires (RED/BROWN) connected to a switched +12 volt source and the positive side of your reverse lights; grounding of those lights should be local to the bulb socket.

WIRING INSTRUCTIONS AND PLUG CONNECTIONS

Red Wire: Fused ignition switched +12 volt connection to provide power for reverse lockout and speed sensor functions.

Black Wire: Ground connection for reverse lockout and speed sensor functions.

NOTE: It is extremely important to connect this to the battery negative terminal or engine block ground to avoid any electronic interference which could disrupt the speed sensor signals and give false readings.
Purple/White (output 1) & Purple/Yellow (output 2): These are both speed sensor outputs, and only needed when using an electronic speedometer or other module that requires a speed signal input to operate. You can utilize just one or both depending on your needs. They both are programmable based on the needs of the equipment they are sending signal to. If only one is used, cap off the other and secure it. Output one is preset at 40 pulses per revolution and option 2 is preset at 16 pulses per revolution. Contact your gauge manufacturer if you do not know what pulse input is required.

Red/Brown (2): Reverse light power input/output. If using reverse light feature, these 2 wires work in conjunction with each other. They both are tied together so there is no way to connect them wrong if you hook them up to the correct sources. One wire will need to connect to a switched +12 volt source and the other will need to be connected to the positive (+) side of your reverse light bulb socket.(Does not matter which one connects to which) Power will be sent to this connection only when transmission is in reverse gear. The grounding of your reverse lights will be done at the bulb socket through a chassis ground. If you are not using reverse lights you can easily remove this part from the harness altogether as it is not connected to the main harness plug.

The three terminated connectors on the harness each have one specific location and cannot be interchanged. It is a good idea to plug them all in even if you are not going to use one or more of them.

Included in the package is a zip tie with clip. This can be used to help secure the All-In-One harness to the case of the transmission.

The epoxy sealed control module should be attached to the transmission using the bolt that fastens the speed sensor clamp. Do not overtighten this bolt.

Note: Some older Magnums have a rubber shipping plug in the mechanical speedometer port. Do not use the factory rubber plug. We offer a billet speedo plug to replace the factory installed rubber plug in the mechanical speedometer port.

The main controller and harness can be separated for service or installation reasons. To disconnect the harness simply slide the red tab away from the connector, then press down on the small black tab while gently pulling the connector away from the controller.

The All-In-One harness has a built-in fuse located near the reverse switch connector. This is a 3 amp fuse to protect the circuit board inside the controller. Removal of the fuse link or swapping to a larger fuse size will void any warranty. We recommend using a zip tie and attaching it to the empty case hole directly above the reverse light connector.

MOBILE BLUETOOTH APP SET UP

Please read this section very carefully. Failure to follow the exact connection procedure may result in an error and the phone not connecting to the All-In-One. The harness is equipped with a Bluetooth radio that will connect to your smart phone along with an app we have developed for Apple or Android users.
Go to the Apple App Store or Google Play Store and search for Bowler Performance Transmissions.
Then download the Bowler Reverse Lockout Setup. Once you have the App loaded onto your phone you can pair it to the All-In-One. To connect your phone to the All-In-One, first be sure the 12v + and ground wiring connections are made from the harness to the vehicle. Second, ensure that your phone’s location services, and Bluetooth connection are turned on. Next, switch power on in the vehicle to activate the harness, then open the app on your phone. Depending on your type of phone you may be prompted with some questions about accessing the devices Bluetooth, and/ or location services.
Be sure to answer YES or OK to all questions otherwise the connection will fail.

When you first open the App it will prompt you to connect your phone.
Be sure your location services & Bluetooth is enabled on your device.
Once you see the ID and RSSI, touch the screen to connect.

Once you have the phone connected to the All-In-One it will take you to this Main Menu screen where you can select which feature you need to adjust.
Start with the Basic Setup menu first.

Once you are done with your basic setup, press the back tab to go back to the main menu.

The Basic Setup screen allows you to input the specifics needed for the All- In-One unit to correctly interpret the information it is sending.
Either touch the screen on the numbers to manually enter the correct information or simply press the arrows up or down to change the value setting.
You will only need to input the
Tire Diameter and Final Drive Ratio.
The pulse count on this screen does not need adjusting.

Next select the Speedometer menu.
This will allow you to adjust the pulse signal output to match your specific requirements for your speedometer.

This is specified by your gauge manufacture and should confirm with them when changing this setting.
The All-In-One is shipped with the default settings for Output 1 as 40 pulses per revolution and Output 2 as 16 pulses per revolution

The Calibration ratio is a very fine adjustment and will allow you to fine tune your speedometer as needed.

There is really no reason to change any settings on the Reverse Lockout Solenoid. The default settings are recommended, which will allow the shifter to easily go into reverse from 0 – 4 mph and will have the spring detent to make going into reverse difficult above 5 mph.
You can change the lock or unlock speed as well as the delay if desired,but not recommended.

We do offer a positive lock Reverse system for race vehicles. If interested, please call 618-943-4856

The diagnostic tab is not recommended for anything more than live data from the module for testing or diagnostic purpose.

Use the disconnect option if you need or want to unpair your phone from the All-in-One Harness.

Advanced options are currently disabled and not needed.

MAGNUM XL CONVERSIONS IN S197 & S550 MUSTANGS

If you are using the All-In-One harness to connect your Magnum XL to your OE Mustang speedometer, please note that in order for the cruise control to work properly you must adjust your ECM/PCM settings to update the gear ratios from their original values to match the gear ratios of the model of Magnum XL you are installing. The All-In-One will correctly calibrate the speedometer, but the cruise control is based off engine RPM in a specific gear, and we cannot correct a cruise control issue with the All-In-One. The original transmissions utilize a different gear ratio set than the Magnum XLs and the All-In-One cannot compensate for that change. Some have found that using the GT500 tune as a base will allow you to make the corrections needed. Please contact an engine tuner to have them recalibrate your ECM for cruise control operation.

The 2011-up Mustangs equipped with the Getrag MT82 manual transmissions require a digital speedometer adapter/calibrator for two reasons. The first is to convert the two wire output of the Magnum XL to the Mustang three wire harness. The second is to increase the pulse count of the Magnum XL from 12 pulses to 36 pulses to match the MT82 output. We recommend cutting the factory connector off and soldering the signal wire directly to the All-In-One harness wire, then shrink wrap and loom the wires for added protection.

In the chart below you will see the color codes for your specific year of Mustang. The primary concern is the connection to the digital signal into the ECM. The All-In-One contains 2 output wires (purple/yellow or purple/white) either one of these can be connected and then have the signal output manipulated to 36 pulses via the smartphone app so that the speedometer will read correctly. Connect only the VSS output of the All-In-One to the Digital Signal in ECM wire. Power is best connected to a clean, switched, 12+ voltage source with the included fuse link and Ground should be a dedicated chassis ground connection or directly to your battery’s negative terminal. Avoid tapping into any power or ground source shared with audio components or fuel pumps. Do not use the old power and ground sources on the OE connector for the MT-82. The 12v ECM and Signal Ground wires in the factory harness can be capped off and not used. *Special note for the 2019 and newer Mustangs: please do not try to use this harness on a 2019 and newer Mustang. Due to the unique nature of the wiring and electronic systems on the 2019 and newer Mustangs, this All-In-One harness will not have the correct outputs to operate correctly in these cars. We currently do not offer a solution, please check with the supplier of your Magnum XL conversion for an alternate adapter.

GM FACTORY SPEEDOMETER OR OE STYLE SPEED INPUT SYSTEM (CONNECT & CRUISE LS WIRING)
In the factory GM installations where an electronic speed input is used in the factory harness you will typically find a two wire connector that carries a yellow and purple wire pair. Sometimes the colors are different, so look for the one labeled “high signal” for connection to the All-In-One. Since the All- In-One harness utilizes a single wire speed signal output you will want to connect the purple/yellow wire from the All-In-One harness to the purple(high signal) wire of the GM harness, then simply ground the GM yellow(low signal) wire. That will give you the input you need to correctly feed the GM speedometer.
From there you can adjust your app settings to ensure that the speedometer is reading correctly, most all GM installations will require a 40 pulse output setting in the app.

If you are using a factory GM speedometer and have any issues such as low speed reading or no speed reading, please contact us. Some OE systems require a capacitor and diode to be wired in series with the VSS output wire. We can supply the components and a wiring diagram as needed.

TROUBLESHOOTING SOME COMMON ISSUES

• If you are using a phone or tablet that is more than 5 or 6 years old you may experience trouble connecting to the Bluetooth radio. The change in Bluetooth technology over the years has made some older devices unable to connect. Try a newer device to correct the connection issue.
• Always be sure the device’s location services and Bluetooth are on and active. We do not use any of the location data for any reason, that feature allows the Bluetooth radio to connect easier by being able to locate the device that is within range.
• Be sure the vehicle battery is fully charged and producing good voltage. A weak battery that is producing under 11.5 volts will not be able to provide enough power to activate the All-In-One processor.
• If you are still having trouble with getting your device connected to the All-In-One. Please have your device model and software version handy then give us a call at 618-943-4856.
