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.
