Toyota MR2 Message Board - View Single Post - Help! Problem with 94' USDM motor to gen3 PowerFC install!

My problem must definitely be with my 94' mr2 harness, to gen3 PowerFC. When I turn the car on, I can hear a buzzing noise that doesn't stop. It seems to be the power steering is my main first guess. There are probably more problems, but this is my first issue I need to solve.

I also grounded my MAT sensor to the chassis, which is probably incorrect. I read through mrlaws posts again, and at first I didn't understand how to ground to E2, when it is a main ground, but I noticed he put "share with others" or something to that nature, so I will be doing that.

Also, mrlaws post is for 91'-92' mr2's, while mine is for 93'-95' mr2, and there are actually more similarities with the wiring to the gen3, but still I can't get the harness right.
