No.

The harness can be fished out through the hole in the firewall.

You will have to find the ground wire and the ECU relay that are attached up high on the pass side kick panel area in the interior though. Once those are loose, you just fish the harness out.

So, what harness did you use for the SEFI? I'm about to purchase a 85 5.0 CFI car and I have the injectors, fuel rails, and intakes from a Mustang laying around.

I was just saying I plan to do the same swap with leftover Mustang parts, not sell the stuff. What engine harness did you use?
