I'm working on the pin list for making the 99 GST ecu work with the 97 Galant engine harness. Here is what it looks like so far:
Added:
Pin Function
3 Fuel Pressure Solenoid
11 Turbo Wastegate Solenoid
16 Boost Meter
52 Ignition Timing Adjustment Connector
78 Knock Sensor
Switch
Pin Function
Galant 58 to Eclipse 31 Engine Ignition Signal
Contrary to suggestions in other threads I do not see a reason to switch injector wiring. They appear to be identical.
Replace
Pin Function
4 ISC Coil A1
5 ISC Coil B1
10 Ignition Power Transistor (A to coil for cyl 1 & 4)
17 ISC Motor Coil A2
18 ISC Motor Coil B2
23 Ignition Power Transistor (B to coil for cyl 2 & 3)
I'm replacing all the ISC wiring because I'm using a 92 Eclipse NT throttle body which has a connector that matches the 2gA wiring harness I have.
Remove (Mostly because I'm a manual trans)
Pin Function
7 Torque Reduce Execute Signal
43 Torque Reduce Request Signal 2
46 Torque Reduce Request Signal 1 (Why would I want to reduce Torque?!!!)
61 Fuel Tank Differential Pressure Sensor (Not used in GST pin diagram I have)
Everything else matches up as far as the ECU is concerned. What I haven't checked yet is if the 7gA and 7gB harnesses match each other at the rest of the connections. That will take some time to verify and will likely be much more of a pain in my ass.
