Parking Brake wire with TV - 10/11/2007 10:42:19 PM    95_4door Posts: 286 Joined: 9/16/2007 Status: online My buddy is installing a flip out tv into his 04 Impala. There is a wire that you are supposed to hook up to the parking brake wire so it only works with the p.brake on. We are trying to bypass that feature. If we ground it it doesn't work. If you put it to +12 v, it doesn't work either. We even tried hooking it up to a 5 volt source and that didn't help either. If we hook it up to the p.brake wire, then it works great. The only way we can seem to get it to work without being wire to the p.brake is to ground it for 3 seconds, leave it open for 3 seconds, and then ground it again.?. Does anybody have any idea on how to bypass this? We have a toggle switch hooked up for now, but it looks kinda tacky. _____________________________ Bill 1995 Chevy Blazer 2wd 4 Door (was 4wd) v8 Swap Post #: 1

Unless the park brake light is an LED in the car... Try connecting the wire to the same wire that's used to get the stereo to power up... _____________________________ (in reply to Chevy Lover) Post #: 3

For units that just require you to engage the brake, they usually can just be grounded. Others (like Jensen/Phase Linear, you know, the cheap crap) require a sequence of having the brake on and off a certain number of times. If that's the case, you can permanently bypass those with a code but it will reset when the unit has no power ie changing the battery, unclipping the harness, etc. _____________________________ 2001 Blazer ZR2 45k Pioneer DEHP3900MP Polk DB 6501 Polk DB 691 Polk MOMO 12 Kicker 08ZX3504 Kicker 08ZX4001 (in reply to 95_4door) Post #: 7
