Quick Head Unit Install Help Needed

I just bought a pioneer avh-p3300bt, my first question is do i connect the ground wire on my wiring harness to the longer ground wire on the head unit's wiring harness, second, where is the best place to put the ground and thirdly, whats the best way to do the parking break bypass on my head unit?

 

best way to do the bypass for that pioneer is to get a relay from like autozone or whatever. pin 85 and 87 goes to ground pin 86 goes to remote wire (blue white wire from radio) and pin 30 goes to parking brake wire (light green).... and im kinda confused on what you are asking about the ground wire. connect the blk wire from the pioneer to the blk wire from your aftermarket toyota wiring harness connector

 

Yeh i kinda feel like an idiot about the ground wire now, but i figured that out and everythings installed and working fine, i just gotta go buy a relay now, thank you for the help

 

You can also wire in a switch for the the bypass. Its pretty easy too.

 

yea the switch will work too but the relay just gives one less thing you have to worry about outside of your dash you know the realy does it automatically for you and btw i am not liable for bypassing your tv you should only do that at your own risk. and remember it is illegal in most states to have any monitor playing video that is in view of the driver. but on a lighter side it is nice for my little girl to be able to watch your baby can read at least til i get an overhead flip down dvd for her
