View Full Version : avh-p4000dvd e-brake bypass

12-27-2008, 08:37 AM
i installed one for my friend, and i think its weird how you have to bypass the e-brake on these....you cant just ground it, you have to hook it to a toggle switch... if u turn it on and the e brake is grounded, youll only get sound, no video.

what you have to do is hook a ground to a toggle, and the e brake to the toggle. u have to have the switch OFF, so the e brake ISNT grounded upon turning on the HU. then once the HU is on, you can flip the switch to ground the e brake wire, then itll let you watch videos with the e-brake not engaged.


oh, and installing one of these in a scion tc has to be the easiest thing ever lol....you use the factory brakets on the stock pioneer HU, and the screw directly to the new pioneer and bolts right up perfect

i put his switch in the glove box along with his ipod wire from the HU (there was a hole from behind the radio, into the glove box) so i ran the wires through that.

and btw, i didnt understand one thing you said except "where did you mount the switch"

I just bought the little box off of ebay and it works fine. No having to mess with a toggle switch or anything.

its fun to wire up a switch there is some cool one's out there. what u pay for that "box'?

12-27-2008, 09:20 AM
what box did you get?

he had a switch in the car on his remote wire he used with the stock HU, so we took that off since the new radio has a remote wire he hooked it to that, and we used his switch for the ebrake. before with the stock HU, he had his amps remote wire hooked to the battery, on a toggle switch, rather than trying to tap into the factory wiring and fking something up
