well, i still have the 86.5 harness and ecu, but i'll need new sensors cuz the others were old and broke in the swap. got rid of the old motor anyway. but these pieces will work with the new motor???? one thing i don't understand is that with both an 86.5 and 90 temp guage sensor, my guage...

are you guys sure the 86.5 harness/ecu/sensors will work on an 89-92 motor. absolutely positive???? if so, the only problem i should have is splicing the harness to the distributor, since it changed. unless of course i put an 86.5 distributor on it, but i don't know that i want to do...

well, pretty sure the 89 harness was crap, not sure why...but the 86 sensors, including the two on the thermostat housing and the connection for the distributor don't seem to work at all on the new motor, with either ecu. any idea why i don't have the connections on the harness for the vacuum...

tried that to begin with, obviously with the old ecu too, and something reads wrong. i swapped the injectors/distributor and the engine must have not liked the readings at the computer end, because that's when the buzzing started. 89 harness doesn't work with 86 ecu of course, so i got the 90...

Hey everybody. I have an 86.5 which i burned the motor up first week i had it. It'd been sitting for two years when i bought it so it wasn't a big surprise. i threw in a jdm replacement, but it ended up being an 89-92 motor. i've got a 90 ecu in place, and an 89 harness . the harness doesn't...

Here's my problem. Car's an 86.5 I burned the motor up racing an 03 vet a week after buying the car. I ordered one of them low mileage jdm's but i never specified a year. so now i've got an 89-92 motor(not sure if 89 or 90-92) a 90 ecu, and the old harness that doesn't work. If anyone has an...

5-speed, na? If so, how much you want for it?

Does anyone know of or have a 90-92, non turbo, 5-speed, engine wiring harness for sale? My supra has been parked for 8 months because I can't find one
