94-95/86-93 distributors

[stangster50]

i put an sn-95 style engine in my 90 notch. i was going to use the sn-wiring harness/computer, but i found and bought a 90 harness. the problem is, i still have that sn-95 distributor with the different plug on it. is there any way i can cut/splice the wires, or am i going to have to spend even more money? if so, can somone tell me which wires to splice together? thanks.

It won’t work with a 95 model TFI module because the pin arrangement is different. You will need to make your own
adapter harness to use the 95 distributor with a 86-93 TFI module.

According to the diagram, the wires coming out of the distributor are:
Red/Lt green = Hall effect sensor power
Black/Lt blue = Hall effect sensor ground
DK Green = Hall effect sensor PIP signal out.

Wire those three connections to the 86-93 TFI module as shown in the first diagram and it should work. Leave the other connections not connected, tape them up or even better, cover them with heat shrink tubing.

You may have some problems making the wiring waterproof. Drive in the rain with a poorly made harness and you could be stranded out in the middle of no where.

The remote TFI module will need to be securely mounted on some type of large aluminum finned heat sink to keep it from overheating. TFI modules are sensitive to overheating and may fail or cause the car to run poorly.

Did this work?? I’m wondering if I can use a nice Accel billet distributor out of a 93 on my 94, and would need to rewire also. Please let me know

i assume this works with a 94-95 harness and a '97 5.8 distributor.
