Yes I have the plug to read codes
coolant temp 195
Tps sweep on old tps replaced with new.
Don't have MAP I have a BAP the harness is off a 89/90 mustang.
Checked voltage on sensors they vary with temp and positions. But I can say they are getting voltage from computer.
the TPS voltage was a tad high 1.2 to 1.25 but it isn't adjustable like some of the older ones were.
The wiring diagram is on veryuseful.com for 89/90 mustang
I have air temp sensor on intake runner#5 I think the newer models 94 and up had a air charge sensor mounted in the air box is this what you are talking about if so no my wiring harness doesn't have a plug for that.
Intake manifold ,injectors (19lb.),harness, distributor, BAP,fuel rail all from donor 89 mustang. fuel pump Summit Racing, mass air from 90 crown vic.
computer reman. from local auto parts chain. I hope this helps. If I missed something please let me know. p.s. I did read the codes twice but most of them were disconnected emissions and others were very vague in the code book for OBD1. probably just me, I need a complete explanation I'm not a professional!
