I need help with some harness issues. My gauge cluster does not work and I found out that I need to connect the M1 connector under the dashboard, but the problem is I don't have one. Actually, all my engine harness plugs that come into the cabin with the ECU plugs don't match the wiring diagrams' plugs or the body harness plugs in my car.
Does anyone know if there were different body harnesses for supras? I was under the impression the only differences were in years for the engine harness.
Do these connectors look familiar to anyone?
^Two from the body, the small one is the M1 connector and the big one connects to a big one from the engine harness. Just can't find the other end of the M1 connector.
^These are the 4 connectors that come from the engine harness along with the 3 ECU plugs. The big square one connects to the big square one in the first picture but the rest are a mystery.
These are just some random connectors at the left side of the glovebox area I can't figure out, they aren't really a priority and I think the white ones may be for TCS.
My car is a late 89 N/A, and I'm not sure if it was originally 5-spd or auto.
My engine harness is a weird spliced up one that is supposedly from a late 89 turbo auto, but I can't be sure.
The dashboard harness (if it comes in to play) is also the original one in the car.
Thanks.

yeah you guys are right... I tried splicing some of the wires from the harness to the other end of the M1 from the body (which I do have) and neither of the two black wires from the engine were the tach wire. I'm actually considering just running a wire from the ignitor to the gauge since I can sort of live without everything else but have to have the tach.
