Fox harness with a (i think) a T4MO. From what i saw, old tuner moved the 3 wires necessary at the pcm for that swap, which requires the fire order change in the tune; as per decphia's direction.
"MINIMUM REQUIRED to be moved to successfully operate an SN95 (94-95 5.0L V8) CBAZA Strategy ecu using a stock 89-93 foxbody harness.
This will allow you to run the T4M0, U4P0, S4M1, J4J1, W4H0, ZA0, and FCLO ecu's instead of using the A9L, A3M, A9M, X3Z, D3D, AP9, or A9T ecu's.
Note: If you would like to be able to interchange between a GUFB and CBAZA ecu, pins can be added and the wires tapped to existing wires in lieu of moving pins.
move pin 52(inj-8) to pin 39 (empty slot)
move pin 42(inj-7) to pin 35(empty slot)
move pin 29(hego-1) to pin 44(empty slot)
If using the high speed fan output on a foxbody ecu move pin 41 to 32
OPTIONAL
tap Pin# 46 to ground do not remove or cut it this is signal return (ground), most fox harnesses have grounding issues, tapping 46 to ground will resolve most ground issues."
Highly recommended but not necessary.
There is a catch though, in order to do so without having to swap more pins around a tune is required, not really a tune just a few values need to be changed.
You must:
DISABLE: ccd (optinal), fpm, am1, am2, canp, octane, smog, and thermactor (smog pump)
change firing order to 1-6-4-2-5-8-7-3
change injector ouput ports to: 00222002
If your wondering as to why change the firing order to the above which appears wrong, its because we didn't move all the injector wires but only the two we needed.
so for reference this is what we now have
Code: Select all
Pin# Inj# ECU Output# Firing Order Bank
58 1 1 1st Passenger
59 2 2 4th Passenger
12 3 6 2nd Passenger
13 4 7 7th Passenger
14 5 8 6th Driver
15 6 5 5th Driver
35 7 4 3rd Driver
39 8 3 8th Driver

As you can infer, the Injector Output Port will need to be updated as well to identify which hego controls which injector.
