Gauge cluster not working

[David48]

I google searched multiple times, searched on here, and asked in the small questions thread but I'm still stumped.

I just got a new vert and swapped the engine, tranny, engine harness, and lower harness from my old coupe. I had this same problem with my coupe as well so I imagine it has to do with one of the things I mentioned swapping. None of my gauges work, and not a single interior light will light up. It's not the TCU since everything but the speedo worked before I swapped over my motor.

Whoever can diagnose the problem, I'll paypal you $5. lol I'm desperate.

the plugs that are up by the battery might be wired wrong. not really sure on which one supplies power to body harness but that's where i would start looking. what motor do you have?

Make sure the TCU is not burnt. it might look fine but its most likey burnt..

That might be it since they aren't properly wired in, but then again wouldn't that keep my brake lights and fuel pump from working? Sorry I forgot to say, it's just a simple dual cam for dual cam swap. I do need to check the brown ecu plug again to make sure it's plugged in all the way.

I doubt that's it. The lights worked before I swapped the motors, and none of the radio plugs were touched together. Next time I have a chance I'm going to try the tcu on a friend's car though.
