To start with I have 79 Z28 with a lq4 and a 4L80E out of a 2003 Silverado. I think I have all the wiring working correctly except the NSS. I have about 1200 miles on the car and everything is working good, except I can start it in any gear. I have the PRNDL switch hooked up to the trans, and all the gears correspond correctly in HPTuners, which I also have set to only start in Park and Neutral. Is there something I am missing? I am using a B&M quicksilver shifter, so I can mount a micro switch on that, but I would rather do that as a last resort. Do I need to tie the factory purple wire under the dash to something on the computer side? Thanks!

I assume this will work on 4L65 too? ( 70 camaro Ly6)
