anyone have a link to a diagram on how to bypass the parking brake for video watching? I dont currently have the parking brake wire installed to anything so i cant play any video but I need a diagram along with a parts list of what i would need to make this happen. The guy at best buy says i need to have a switch that i have to flip everytime i start the car but i'd prefer one that i didn't have to **** with everytime. I drive an 07 focus zx3 5 speed, any help is appreciated!
I believe pioneers need some kind of delay switch. Guy I just bought my pioneer dd included it.
A toggle switch from the parking wire (green) off the deck. To the ground works Just switch on and off

[/COLOR]relay give me a minute and i post up adiagram
relay pin 86-ground
pin 87-ground
pin 85-remote
pin 30-parking brake
is this accurate? that simple?Quote:

Tap into the ground on the back of the HU, run ground to pin 86 and 87, make a lil jumper wire
Tap into the remote wire on the back of the HU, run it to pin 85
The green wire on the back of your HU, or whatever colour the parking brake wire is, goes to pin 30
Don't do a switch. Relay, automatic, no need to do anything.
the pioneer requires a ground signal to work? it seems like if you are hooking to the pb wire it would read a hot wire to turn on, at least that's how my jvc avx77 works.
Go on ebay and buy a prewired relay for the pioneers, it's like $9 shipped... Unless of course you need it done asap.
The pioneer avh p8400bh requires a double pulse relay to work, and probably other new HU's
You are absolutely wrong. Sorry. ALL Pioneer AVH units are bypassed via a relay. The AVH units can NOT see a ground on the e-brake BEFORE the unit turns on (which if you have your e-brake up when you turn on the car, you'd need to technically double pulse as the e-brake is up, then you have to put the e-brake down and back up).Quote:

The reason you're using the remote turn on and not a constant or accessory source is when the radio turns on the remote turn on is a delayed turn on (the remote turns on a couple seconds AFTER the radio). This way the radio/e-brake wire sees no ground on boot up, then ground a few seconds after.
Lets review:
A relay has 5 terminals
85 and 86 which are the coils (one is going to be a - trigger while the other is a +)
30 is common (which is attached to 87 and 87a depending on whether the relay is energized)
87 is normally open (that means when the relay is not energized the circuit is open - i.e. not connected to 30)
87a is normally closed (that means when the relay is not energized the circuit is closed - i.e., connected to 30)
So a regular relay would work for the AVH?
One of these is said to work. http://www.amazon.com/Parking-Overri...=3IGCO6ZIB7NJF
I just put a momentary interrupt switch on mine.
