so i bought a 1992 non turbo automatic car that has been swapped with a 7mgte motor and an r 154 trans the guy has it wired up some how using the na wiring harness and the na computer and the car runs fine somehow! which i find unbelievable but thats besides the point id like to swap the na harness and na computer out for the right wiring harness and ecu! the motor and tranny is out of a 91 supra and the car is a 92! what wiring harness would i have to get??

You need a 92 wiring harness, All the motors are the same except newer castings and turbo motors having turbo drain and feed and oil squirters drilled and tapped.. All heads are the same just the intake cam is different.
so all i need is a harness and an ecu out of a 92 turbo supra right?

i have an ecu and wiring harness out of an 88 turbo would that work or is it just the 92 wiring harness and ecu that will work?mikehockenberry88;1715659 said:
89+ have a better tuned ecu.
You need the 92. It has the wiring for the airbag and all that. Its also a shit load easier to just buy the right harness and plug it in rather than trying to sort out wiring and plugs to make it work.

Yellow pluged Ecus (87-88) Grey Plug (89 <- gets its own year), (91-92) i think a 91 harness would work as well
91 would work. The ecu doesnt matter so long as its gray plug.
Its just the harness and it really is better to just match up the year and options. Like abs and if your using auto you need a auto harness and ecu but hes r154 so it doesnt matter.
Of course 87-88 are the same so that doesnt matter.

There is 2(that i know of) different plugs for gray plug so it could have been a 89 or 90 and he thought it was a 91.
ill just buy one for a 92 turbo 5 speed and be done withe it! thnaks for the info!

good luck, there's only about 1000 92 Supras, and not all are turbo..
you can look for a 91, and you might have more luck, as there were around 5000 of those..
