Im getting very close finishing my 4v swap but I ran into a snag. I have read many swap forums about swapping the wires on the coil on plugs but my issue is that Im using the factory 01 GT harness and I have cobra COP but the plug from the harness only fits half way onto the cobra COP. I can't find anyone with this issue as far as the write ups go. Even with the wires removed, the plug doesnt fit.

Anyone else have this issue? Really want to get my car running in a month.

I keep slacking on updating this. I figured out the issue. The factory plugs are different on my car. After talking with a mustang guru, my 2001 is the early model where the MAF and intake air temp and separate and other small differences, like these cop plugs. My cops have notches on the inside of the plugs which prevent any other cop to be plugged in. I ordered cop repair harness and it fit. Here are the pics I took of the factory one vs new one I bought.

Thats strange. I have done this on a 2000 model, and while I did modify the maf wires, I had no issue with the cop fittings. Glad you got it figured out. Good luck with the rest of your swap. Thanks for updating the thread with pics too for people to referrence in the future.
