I am wondering if the stupid e-brake green wire thing is wrong and the pairing wont work because I'm not safely parked. What exactly did you guys do with the long green e-brake wire that is supposed to go to the "power" side of the e-brake (as per 8500NEX installation schematic). Its kind of confusing with TO2 harness saying for light/green to connect to HU harness, yet the HU harness has a long wire and says to connect to parking brake.

What is the long green wire supposed to go to when you also have a TO2 harness?

Anyone have any clarity on this ebrake wire?

Only thing I can try is to unground the light green ebrake wire since that is the only questionable wire connection and maybe that is screwing with the safety must be pulled over before you can perform a phone setup process.

Crutchfield is totally supportive and have offered to exchange the head unit in case of defective or to simply return it. Great customer service.
