Product Information
29-UC-050-CHR1 Chrysler Steering WheelControl Interface
The 29-UC-050-CHR1 Chrysler Steering Wheel Control Interface is a device
that allows you to retain the factory steering wheel controls when replacing
the original head unit in your Chrysler 300C (05-10), Jeep Grand Cherokee
(05-08), or Compass (06-11). The interface box has several input and output
connectors that allow it to communicate with the car’s steering wheel
controls, illumination system, ignition system, and CANbus network. The device
also has a patch lead that connects to the aftermarket head unit and allows it
to receive the control signals from the steering wheel.

| 11 | Grey | Speed Pulse Output |
| 12 | Purple | SWC RES Output |
| 13 | N/A | N/A |

Jumper Settings
The interface box has two jumpers (J1 and J2) that can be set to customize the behavior of the device. By default, the jumpers are set to suit most vehicles and should not need to be changed. However, if you are fitting an Alpine head unit, you need to set J1.
| Jumper | Position 1-2 | Position 2-3 |
|---|---|---|
| J1 | Alpine | N/A |
| J2 | Negative Handbrake (not all vehicles) | Positive Reverse Output |
Supported Head Unit Brands
The device needs to be set to the brand of head unit you are fitting. The number of flashes between pauses corresponds to the make of the head unit. Press the VOL + and VOL – buttons on the car’s steering wheel to increase or decrease the number of flashes. When you have the correct number of flashes, press SEEK+ to confirm, and the LED will go to a solid green.
| Number of Flashes | Make of Head Unit |
|---|---|
| 1 | Clarion 3.5mm jack |
| 2 | Kenwood 1 wire |
| 3 | JVC 1 wire |
| 4 | Alpine 3.5mm |
| 6 | Pioneer 3.5mm jack |
| 6 | Resistive 2 wire |
| 6 | Resistive 3.5mm jack |
| 7 | Sony 3.5mm jack |
Product Usage Instructions
- Connect the cables to the interface box and to the car, and the patch lead to the 4 pole black connector (this is attached to pins 4, 8, and 12 of the control box).
- Connect the two 8 pin ISO connectors and the patch lead to the aftermarket head-unit.
- When connected to the car, the interface will automatically recognize the vehicle. The green LED on the interface will repeatedly flash once followed by a pause. If the LED flashes red, it may be necessary to swap the CAN wires. Some vehicles have the CANbus wires reversed. Bullet connections are inline on the green (2) and white (9) CAN wires for this purpose.
- You need to set the interface to the brand of head unit you are fitting. The number of flashes between pauses corresponds to the make of head unit. Press the VOL + and VOL – buttons on the car’s steering wheel to increase or decrease the number of flashes. When you have the correct number of flashes, press SEEK+ to confirm, and the LED will go to a solid green.
- If you are fitting a Chinese or resistive programming head unit, set the number of flashes to 6. Confirm the setting by pressing SEEK+. Now press the reset button 5 times, and the interface will start to flash yellow (this allows prolonged pressure on the steering controls). Using the radio’s resistive learning menu, you can now learn and memorize the buttons. Wait at least 5 seconds between each button press. When finished, turn the ignition off and on, and the LED will go back to solid green.
- To reprogram the interface for another head unit brand or if the light is solid green before you have had the chance to set the head-unit brand, push the reset button in and keep it pushed in for 10 seconds, and then release the button. At this point, the LED should start to flash green.
- The reverse output (blue wire) is only needed when fitting a reverse camera to the new head unit. The grey speed pulse wire is needed when fitting head units with built-in satellite navigation and some Kenwoods. If not required, these can be insulated and ignored.

You need to set the interface to the brand of head unit you are fitting.
The number of flashes between pauses corresponds to the make of head unit, see
the table below for the number of flashes needed for each one.
Press the VOL + and VOL – buttons on the cars steering wheel to increase or
decrease the number of flashes. When you have the correct number of flashes,
press SEEK+ to confirm and the LED will go to a solid green
For Chinese and resistive programming head-units.
Set the number of flashes to 6. Confirm the setting by pressing SEEK+. Now
press the reset button 5 times, the interface will start to flash yellow (
this allows prolonged pressure on the steering controls ). Using the radios
resistive learning menu you can now learn and memorize the buttons. Wait at

To reprogram the interface for another head unit brand or if the light is
solid green before you have had the chance to set the head -unit brand.
Push the reset button in and keep it pushed in for 10 seconds and then release
the button. At this point the LED should start to flash green.

Setting the Jumpers
The Jumpers are on the PCB inside the interface box. By default they are set
up to suit most vehicles and should usually only need to be changed if fitting
an Alpine head unit. The jumpers are set by moving them between positions 1
and 2 or positions 2 and 3.
| Position 1-2 | Position 2-3 | |
|---|---|---|
| J1 | Alpine | All other Radio Manufacturers |
| J2 | Negative Handbrake (not all vehicles) | |
| J3 | Positive Reverse Output | |
| J4 | ||
| J5 | CANbus Handling |
The Reverse and Speed Pulse cables.
The reverse output (blue wire) is only needed when fitting a reverse camera to
the new head unit. The grey speed pulse wire is needed when fitting head units
with built in satellite navigation and some Kenwoods. If not required these
can be insulated and ignored.
The speaker adapter (brown ISO connectors)
If you are not getting phone or navigation audio through the front speakers,
add this extra cable to swap the audio output from back to front. This is most
often required on cars with original Boston Audio system.
Make sure the patch lead is connected to the 4 pin plug on the interface
and the input on the new head unit. 29- UCCAB patch lead wiring information –
