1991 7MGTE to 1987 7MGTE

Chromemoly · 08-06-2010, 08:24 PM

Here is my predicament..... I have an 86.6 Body, and a 90 GTE engine. Do I use the existing harness on the 90 GTE engine and couple it to the 90 ECU? OR... do I swap in an 88 GTE under-dash harness and cluster, then use an 88 GTE engine harness and ECU. I have all the wiring from 3 different Supras, and clusters from 86.5, 88 GTE, and 90 GTE. Will I have swap in a GTE harness to the engine bay/chassis? I just want the easiest way to achieve working telemitry and functionality.

If I understand you correctly I think it would be easiest to us the 90 stuff to go with the 90 stuff rather than swapping this and that out.. Just seems easier to me. Besides that.. THREAD JACK!

88 ECU and engine harness and GTE tachometer would probably be the easiest route, then you shouldn't have to worry about the dash harness.
