Does anyone have the Metra or Scosche part numbers for the wiring harness adaptor for a 2000 Firebird with Monsoon? Any help would be greatly appreciated. Thanks in advance.

I am having a hard time finding the adapter harness to add an aftermarket deck on my 2000 Trans Am with the Monsoon setup. I picked up two different GM harnesses and neither of them matches. One is the standard GM 88 and up harness and the other is a 2001-2006 gm harness.

I have one of the standard GM harnesses, but it does not seem to work. On the back of the package it also states that it is for up to 99 firebirds. Is there a different one on 2000 and up models?

The factory harness has two 10-pin plugs. The standard 88+ GM harness adapter has one 21-pin plug. Put the two factory plugs together as they were when plugged into the head unit and they will plug into the 21-pin plug (the extra pin space isn't used). They are keyed to only work one way so if they don't fit, turn them over and try again.

Exactly what whitebird00 said.
