OK got it! I honestly think that after moving the door wires back and checking fuses, the problem was I was checking it while sitting there on my stool by the door to check the flashing LED. I didn't even think about it (the driver door was opened) so that must have been it. I closed the door, started right up. Also, I think a few time I barely put the battery terminal on the post since I was frequently taking it on and off.
I had one failed start after all this, but a second button press started it up. It's a cold morning so maybe that's it.
So.....it was probably the bad ground switch all along since that's really the only thing that's changed NOW. Things were moved back and forth but now that's the remaining change. FWIW I did try to reset the tach as well, but the LED didn't flash after the 3-5 seconds like it's supposed to. I also need to figure out how to make it chirp the horn with lock and unlock AND flash the parking lights upon remote start.
So it works, but I need to figure out why the other things aren't working. I had the light flash output from the main 9 pin harness go to my parking lights on the car. and the horn works because the panic button works.
