So i will try to spell this out in as much detail as I can. First off the car runs and drives, only went on a short trip..and o2's are completely unplugged at the moment until I figure this all out. I have been over as many wiring diagrams as possible and read hundreds of threads.
My question is simple. On an 86 MAF swap, using all 86 wiring harness's including the 02 wiring, do any changes need to be made to the O2 harness?
I read all this mess about the jumper loop wire, 6 pin 02 sensors vs our 3 pins, adding a "loop" wire in the 02 harness. Grounding pin 30 to not get a "code 67" and checking pin 47 for voltage at starting / cranking as to not "fry" the ECU's trace wire on pin 46. It just seems NOBODY mentions 86 specifics when talking about MAF conversion and our O2 harness seems to be lacking wires and the NSS is a bit differnt on our cars. Like I mentioned though, it starts, idles and runs okay (needs a tune). I just want to know if I can plug in the O2's and if the ECU will see the signals correctly from them.
Here in detail is what I have currently done.
Car is an 86 GT 5 Speed manual, v8 5.0
Engine is from an 89 Auto, but only used the Engine, A9P ECU and MAF. I DID NOT CHANGE the harness on my car, I left it all 86. Left the 5 speed. tried to steal the new O2 sensors off of the 89 but realized the had a different plug, and I chunked my orig 86 O2 sensors. So in all purposes, this would be a normal 86 MAF conversion using an A9P ecu.
Added 4 wires for MAF to the ECU (pin 9, 40, 50 and 57)
Added 2 VSS wires (my car has cruise) to pin 3 and 6
Added Fuel Pump Relay monitor Wire to pin 19
Swapped pin 11 to 32 and 51 to 38
Hopinf someone on here might have knowledge / insight to this subject specific to an 86 GT.
Thanks all.
