Hey everyone, I'm the new guy here. I have a question about wiring up a new HU. I have an Alpine CDA-D852 (yeah I know, old but it was awesome in my old pickup and it was my uncle's, so I hate to give it up), and I've got all the other wiring figured out, except for one. My GTP has the steering wheel audio controls as well as the HUD. I don't want to lose either (well, I wouldn't mind the HUD) so I'm trying to figure out where I can stick the dark blue wire on the back of the head unit. Any thoughts or ideas would be greatly appreciated. Thanks!!
Will
