Overview

The FuelTech PRO600 Wiring Harness is a complete plug n’ play wiring solution to be used with a FuelTech FT600 ECU. It has all the connectors, relays and fuses directly built-in and can be used with nearly any application with 8 injectors (expandable up to 16 injectors).
PRO600 V8 Harness

The PRO600 is a FuelTech FT600 harness designed for systems with up to 16 staged injectors(dual banks), distributor or COP coils and FuelTech Wideband Nano O2 dual channel with Bosch LSU 4.2 sensors to run sequential, semi- sequential or multipoint injection. It is already wired for 2 FuelTech Peak and Hold drivers for setups utilizing 8 low impedance injectors, for 8 more injectors a secondary injector harness is required. When using high impedance injectors, Peak and Holds are not needed. In this case, only a bypass connector (jumper wires sold separately) is required. There are 2 relays to power the complete system, separating the injectors from the electronics. FuelTech- PR0600 -Wiring- Harness -1

PRO600 V8 Smart Coil harness components
This extension allows the use of 8 individual Smart COP coils(w/ integrated igniter) on the ignition system, it has 8 metri-pack 150.2 connectors, 1 relay and 1 fuse (or 2 relays and 2 fuses on the second generation). Check below to see all of the connectors and where they are connected, as well as instructions and specific information for both generations:
Standard components for both generations:

Main Inner 24-way circular: The Main connector is a 24-way Tyco CPC connector that contains the outputs to the 8 individual coils.
8x Smart coil connectors: 8 Smart COP coil outputs (metric- pack 150.2 connectors) which allows either sequential or wasted spark ignition.

First-generation:

1x 30A Relay: This Relay will power the coils
Outputs B connector: This connector must be plugged into the “Outputs B” connector on the PRO600 harness.

WARNING:
Making changes to the map using FTManager then writing to the ecu with car power on or with a battery charger on it may possibly damage the coils or blow the fuse.

Second generation:

2x 30A Relay: These Relays will power the coils.
Outputs B connector: This connector must be plugged into the “Outputs B” connector on the PRO600 harness, To prevent damage of the coils, the separate red wire must be wired to a yellow output in the outputs C connector, the selected yellow output must be set up as a RPM activated output on the map(refer to instructions below). If no yellows are available, this red wire can be inserted in the vacant pin J or a separate switched 12v (With the risk of maybe damaging the coils if ignition is left on for long periods of time).

WARNING:
When not using a RPM activated output to trigger the relays, making changes to the map using FTManager then writing to the ecu with car power on or with a battery charger on it may possibly damage the coils or blow the fuse.

Setting up RPM Activated Output and testing the coils:
To set up a yellow output as a RPM Activated Output to trigger the coil relays follow these instructions:
On FTManager: go to Engine Settings>Map options>Other functions then check the RPM activated output checkbox, click on it to go to the set up menu, next change “Enable with RPM above” to 20 and Output signal to Activated at 12v, then go to Sensors and Calibration>Outputs and change the yellow output selected for this to “RPM activated output”.
On ECU: Go to Other functions>RPM activated output, first select the yellow output, next select “enable”, then on the last screen change the output activation to Activated at 12v.
When using the test feature on the outputs menu available on FTManager to test the coils, you must first change the RPM activated output setting to 0 RPM, so as to trigger the relays with the engine off.

Outputs

If the system being activated requires a 12v output, the yellow outputs are capable of ground or 12v. If no yellow outputs are available, it’s possible to drive a relay by ground with any gray output to get the proper 12v output switched by one of the gray outputs by following this diagram:

Yellow outputs are the most specialized outputs. They are HALF BRIDGE or PUSH PULL type outputs. This means that they can feed 5A both by negative or positive side. They are important and necessary to control Electronic drive- by-wire throttle (DC motors) and stepper motor 4 wire idle control valves. They also can be used to control any type of LO SIDE or HI SIDE actuator (LO SIDE means the ECU will switch ground to activate the device, HI SIDE means the ECU will switch 12V to active the device). Since it can feed 12V power at 5A, if wired to a relay activating it by ground (from the FuelTech) when turned off, it senses the 12V through the relay coil and feeds back power to the ECU. In this case, it is necessary to run a series diode (4004 or 4007) like the following schematic to avoid this issue. Both ways of wiring this output are described in the following diagrams: FuelTech- PR0600 -Wiring-
Harness -26

There are some relays with a built-in diode, like Hella 003437101.

On water cooled engines, place this sensor near the engine head, reading the water temperature. On air cooled engines, install this sensor reading the engine oil temperature. One of its pins is connected to the battery negative, the other to the white #5 wire. Part numbers: FuelTech 5005100016 or GM 12146312

Meters and adapter wires

Fuel Tech WB-O2 Nano
The WB-02 Nano has a 12-way connector with 3 wire groups. One of them has the connector for the O2 sensor, the second makes the CAN communication with FT600 and the third is responsible for power and analog output. By default, the analog output is set to values of 8.7AFR to 16.2AFR Gas, but can be configured to 5.14AFR to 17.6AFR Gas or 9.55 to 19.11AFR or 9.55 to 58.80AFR or yet 9.55 to 146.9AFR (Gas), if necessary. For further information, check the FuelTech WB-O2 Nano manual.

FuelTech EGT-8
The FuelTech EGT-8 is the module that is capable to read Thermocouple Type K sensors and send the data to the ECU through CAN A communication port. Capable to read temperatures from 32ºF to 1832ºF.

Alcohol O2
The FuelTech Alcohol O2 is a dual channel O2 reader and is designed to read extremely low AFRs, recommended mainly for alcohol engines in drag race application, since it is able to read down to 0.28 lambda (1.79AFR alcohol, 2.52AFR E100 or 4.12AFR gasoline). FuelTech Alcohol O2 has an AMP Super Seal connector. For further information, check the FuelTech Alcohol O2 manual.

Bosch LSU 4.2 Wideband O2 Sensor
The BOSCH LSU 4.2 is a wideband O2 sensor that can be used with both the WB-O2 Nano and Alcohol O2. When using LSU 4.2 with our Alcohol O2 reader, an adapter harness is required, as well as free air calibration. Check the Alcohol O2 manual for further instructions.

NTK WB-O2 sensor – Alcohol
The NTK wideband O2 sensor is designed for high accuracy and low AFR’s, must be used with FuelTech Alcohol O2. This sensor requires an adapter harness and free-air calibration. For further information, check the FuelTech Alcohol O2 manual.

Bosch LSU 4.2 O2 sensor to Alcohol O2 adapter harness
This adapter is required when using the Alcohol O2 with Bosch LSU 4.2 O2 sensors. Each channel of the Alcohol O2 can read a single Bosch LSU 4.2 O2 sensor. To purchase the adapter harness, contact FuelTech. Part numbers: FuelTech 3022000965 or Bosch. FuelTech- PR0600 -Wiring- Harness

Peak and Hold – External Injector Driver

Peak and Hold drivers are designed to control the current on low impedance injectors. The FuelTech Peak and Hold has 4 outputs and in the PRO Wiring Harness will run one injector per channel.
There are 3 different versions of Peak and Hold available to fire different injectors, according to the resistance of the injector. The only differences between the versions are the peak current and the hold current. Considering one injector per channel application: 2A/0.5A – Bosch 1600cc, Ford Racing 1600cc 4A/1A – Siemens Deka 225lb/hr, Precision 225lb/hr 8A/2A – Precision 550lb/hr, Billet Atomizer, Moran Some earlier Moran injectors require a 4A/1A driver. Contact FuelTech tech support to confirm correct Peak and Hold drivers before purchasing. When using high impedance injectors without Peak and Hold drivers, jumpers wires (sold separately, part number 2001000071) must be connected to the Peak and Hold plugs in the harness. If the jumper wires are not being used then the injectors won’t fire since there will be no continuity between the FT600 and injectors.
