I've got access to Alldata and pulled diagrams for a 97 Grand Prix VIN: K and 97 Grand Prix VIN: 1 (SC). They are the same diagram exactly without any variance.
I repeated the process with both models only for the 98 yr model and they are the same there too. They are however totally different from what is shown for the 97's.
Anyone have any ideas on this one? Are the 97 GTP harnesses the same as 98 harnesses?
I'm trying to figure this out because I'm contemplating doing a complete pin out on my current 97 GT harness and adding wires where needed to do my L67 swap. I know I have another thread about keeping my 4T60E and swapping to an HD variant, but now I'm thinking maybe I'll go ahead with a 4T65E-HD. I bought a 97 GTP computer this morning b/c I'm trying to keep it consistent between year models.
