Alright so I'm installing a pioneer sph da210 got every wire hooked up but the green parking brake and purple/white reverse gear signal wire I don't have a wiring diagram so does anyone know where to wire these up?

 

Not using a back up camera so the reverse wire not used. Can I ground the green wire and that will let a the DVD player play while driving or parked?

 

On the parking brake wire, I had to use a relay on my last pioneer radio to get it to work, on my current pioneer just grounding that wire didn't do anything. I bought a video bypass for it on ebay for like $20 and it works perfect

 

I'm trying to figure out which wire is the parking brake so I could just do the normal install till I decide to get the bypass I took the console apart and it says clamp the positive side of the parking brake but what wire ? A picture would be great

 

If you take the console apart there should be a wire connected to the switch on the parking brake. You should see it when you pull the parking brake handle up and there is something that makes contact with the switch. That should be what you're looking for.
