Hey guys I am in the process of finishing my build and I need some help. I have a 1994 mustang motor in my e36 and in 1994 ford decided to Chang up the wire harness. In my e36v8 directions it's telling me to cut the green connector and splice it into the x20 connector. I think i found what connector to splice into but the wire colors are not the same. Has somebody figured this problem out before and can anybody help me? Please see pictures.
I used a 95 engine and harness with my swap. I sent Matt who sells the 5.0 kit what I did for him to add to his document. Send me your email and I will try to get it to you. The easiest thing to do is trace all of the wires that you need to connect from the ford EEC ECU connector and connect them to the BMW x20 connector. There are only 10 to 12 needed to run the engine. The 95 harness has a ton of crap that you don’t need on it (fog lights, alarm) that made making the harness a pain. The 94-95 5.0 EEC hates any and all modifications and that’s why ford guys get rid of them or sometimes pay you to take it with something else. I have a megasquirt that’s going in soon so I can install power adders.
If your looking for clean and easy use a megasquirt and build your own harness. I just redid my harness and removed half the oem mustang wiring for my megasquirt.
I would get a harness from painless performance. Don’t even bother with the mustang harness, you just end up with a hacked up 30 year old harness that doesn’t fit the E36 real well. I Recently changed to a painless harness and wish I would have done this from the get go, it’s a lot easier.
