Thread: engine wiring harness

Anyone know the difference between GT and GTP engine wiring harness?
The dealer lists a different one for 1999, 2000, 2001 GTP engines. Anyone get close enough to these things to find any differences? I need a 2000 GTP harness but have both the 1999 and 2001. I believe i may have a 2000 GT n/a harness but not sure what the difference is between GT and GTP.

TIA

Ok well so the GT engine wiring harness from 1999 has a different abs system which makes the interior plugs fromt he engine wiring harness different on the drivers side there. The 2001 model has different sensors on the motor for some reasons is what Morads told me. The GTP has a different MAF sensor on it and I believe something extra for the supercharger but I don't have one to confirm that.

I'm looking for a 3800 na 2000 Grand prix engine wiring harness myself right now. I hope this helps some.
