Recently bought a 1985 GT with CFI still all setup (non-running). Going to do a carb swap but would like to keep the ECU computer wiring harness intact, since I'm assuming CFI ones are rare.

I have it all removed but there seems to be a bundle of wire still connected somewhere that's not pulling out of the firewall. Screen shot shows removal of main computer connector and black solenoid. Still have that wrapped set of 5 wires (red+yellow+3 white-ish) not budging.

Any idea where these connect to? Worst case I'll just cut them off. Oh also, any trick to keep the firewall boot intact so I can put back in the firewall and plug?

Can you not follow them behind the firewall? Been a loooong time since I pulled the CFI out of my T-Bird but my recollection was I did not cut a single wire and did not pull the dash.

Also, this is a really good site for the 79-86 cars:

It almost feels like that bundle of wires goes up into/behind the dash. Haven't removed anything besides the passenger kick panel. Can feel it doesn't go down to where the computer was, almost up a bit and across.

And yeah all the info I've come across so far was you can just pull it right out - ground, computer connector and solenoid.

Are you serious? You still haven't been able to get on there? I go there daily.

What happens when you click on AeroCoupe's link?

How 'bout this link?

Been up and running for months now. Those guys can get you answered if no one here can as those years of cars are the focus there to they live in that world.
