Engine wireharness confision 88 vs 89

Supra Saiyan · 02-26-2011, 08:27 AM

So this is simple, but I keep getting confused.. I know that an 88 a/t engine harness wont work right on an 89 a/t engine harness..
My question is that.. What if it's a m/t harness from an 89 going on with this a/t engine / transmission..? I feel like I am talking myself in a circle because ive read so much..

BTW I am speaking of a turbo engine harness during this entire thing..

So what else will I need? I don't want to replace the gauges and such as well.. Will I need to do some things with gauges? Will I need anything different.. Or can I just get the 89 harness and the engine and plug it all in..
