Check it out.

I have a 98 base model Firebird 6cyl auto.

I swapped in a complete drive train, motor, 6spd trans, engine harness, and computer and added clutch pedal assembly, all from a wrecked 02 Trans Am.

I now have no gages, tach, or speedo, and my temperature gauge bounces back and forth; that's relative to how fast I'm going, lol, and my cooling fans never come on.

I jumper wire the relay, and the fans work.

I should have gotten a dash harness out of the donor car, but did not.

I know I'm not the first to do this swap so any advice would be appreciated.
