can't bypass my d1. tried grounding empty pin. any suggestions..????

Ground the parking brake wire too

sorry. did ground both wires at same place. grounded ebrake wire (green) and also grounded empty pin. as soon as it hits 10mph doesnt work. i don't remember if i hooked up speed sense, does that matter???

No, speed sense makes no difference. I would next check if your wire in the magic hole is in there securely--sometimes the pin doesn't seat properly and comes loose

thanks ill double check grounds.

Had similar problem, when I went to plug the harness back in, the wire popped out. Didn't notice at first, but had to go back and plug the harness in, then shove the wire back in to it.
