Holy crap, I think you are my savior. I pulled the AOD out of my GT years ago, and threw a 5 speed in along with a 5 speed harness. Ever since I have not been able to run codes.
Are you saying that Need a 5 speed o2 harness AND A9L computer or what? I haven't tried running codes in about a year and a half, but I swear I haven't been able to get the car to throw codes in years.......... Maybe I will go out into the garage after work today, since it finally warmed up, take all of the above pictures I said I would, and see if my car will run codes...........
You get no codes at all? or you can get codes in koeo but not koer because of code 67? how are you pulling codes, Jumper wire and cel light or scanner? Are both plugs at the clutch pedal switch pluged in or does one still have a jumper harness in it?
Try the jumper wire to pull codes threw the CEL light if the scanner won't comunicate and your getting no codes at all. STI to sig rtn on self test port. I have seen scanners not comunicate because of the nds circuit but was still ablle to pull KOEO codes threw the cel light.
if you still get nothing try the factory aod harness if you still have it and have the factroy aod ecu in the car. That atleast should allow you to pull codes, if not it sounds like you lost an internal ground in the ecu. you can check that by adding a ground to sig rtn and reruning koeo test... if you get codes its a ground issue.
While the t5 swap with an aod ecu and harness works Many people complain of idle issues and the cuise control not working properly when its done this way. The ecu uses both the ngs and vss to view load so with an aod ecu you get the hanging or high idle alot when coming to a stop and some get the rolling idle. Theres a reason ford used different ecu's for Autos and t5 cars and its not just because of the timing tables.
When I do a 5spd swap I change every thing now.... trans tunnel hump, t5 o2 harness from the same year, a9l and the t5 harness that runs from the drivers kick panel to the trans. thats the factory correct way. No idle issues, no butchered wiring, cruise control works like its supposed to and you can run both a koeo and koer test. The trans tunnel hump is so the lower shift boot will bolt up. Do you have too? no but if you want everything to work properly its the easist way to do it.
gnvair I remember when I first hit this issue craig couldn't pull codes from my car back in the late 90's I didn't find the cause till years later but I remember craigs scanner not even able to pull koeo codes... I was able to with a jumper but could never get past code 67 for a koer test.... the ngs was unplugged with no jumper so it was allways open, it had the aod 02 harness and an 93 cobra ecu in it at the time so it can be done... its just a half assed way to do it and you get a ton issues. Not to mention if someone Plugged the ngs in like I did when I put a a9l in it years later... poof fried ecu lol. Still have the repaired ecu in it now but all the correct harnesses from a 90 5spd car and every works like it's supposed to.
