park neutral plug I think this is the park neutral plug. The harness that I purchased did not have this. What does it do exactly? It looks like it has only 2 pinks & a black/ground. Can I just wire those to a ground & a power? Thanks for any input.

Correct....[Mine is an 05 Hummer trans w/ a Howell harness]. I am using the PNP sw to trigger a neutral start relay on my 55 Chev.
If you need more info, send me an email..I'll advise as to how I did it.
You may also need the tool to adjust it, so it reads the shifter position correctly.
You can adjust it manually if you have a helper...
Trans in neutral, attempt to start. Yes? Tighten the bolts.
No, move sw until engine attempts to start, when it does, tighten the bolts.
If you need more info, send me an email..I'll advise as to how I did it.

Thanks, I will likely send you an email when I try to finish this up in the next couple of weeks.
Be glad to

The way I understood it (I could be wrong, likely the case), is if your car has the PNP switch under the dash on a stock body harness, then you don't need that plug or tranny mounted switch...The PNP switch on my Gbody is under the dash at the base of the steering column. Someone please correct me if I'm wrong..Going through this right now on mine and hoping to fire it this week.
