what wire attached to the parking brake do I use for a parking brake signal for my AVIC-D3
thanks

 

do you have a light green one? My old pioneer was light green and my new JVC is a light green ...

 

If you want you can bypass that so you have access to the nav menus and can have video play while you drive. All you have to do is ground the light green wire from the d3, then on the seperate rca harness locate the mute wire which is yellow with a black stripe. Remove that wire by releasing the locking tab and move in directly above it into the empty location and ground that wire. Thats it, now you have full function of the d3 while the vehicle is in motion and while parked. Just remeber it is illegal to have video in view of the driver while the vehicle is in motion so just be aware of that.

 

umm.... lol. i just wanna hook up the light green wire coming from the head unit to the parking brake. Which wire by the parking brake is that? thanks

 

It should be the only wire by the parking brake. I saw one of my coworkers put in a nav system the other day. The car he was putting the parking brake wire only had one wire by the parking brake cable. Hope this helps
