So I had installed a 1988ish 5.0 in my 1967 a few years ago, and then added MAF, and switched the computer to an A9l.
I had also moved the MAF and O2 power to all run off a relay to lighten the electrical load.
Then only recently, it was brought to my attention that there is a jumper difference between harnesses that can burn out the computer, make it run poorly, etc. I took my harness apart, and noticed I didn't have a jumper!
I forgot I think I used a 1988 harness. So there is no jumper. Is there anything specific I would have to do in this case? Or should everything be running great (it's not, but that could be a multitude of many other things). Jumper wire + computer selection only applies to 1989+ that came with MAF? I'm in the clear?
If not, please enlighten me!
Thanks guys. Pic included of the back of my plug. The white/pink wire is snipped off. IIRC, that is low oil sensor on the original fox pan?
