steve s Posted September 5, 2004 Report Share Posted September 5, 2004 so.. the alpine video unit has two wires needed for viewing per safety reasons... one is the parking brake wire and the other is the foot brake wire. i've got the foot brake wire tapped into the rear brake light. where would i locate the parking brake wire? i don't recall a lamp for the parking brake on our 850, so where would the wire be? i know there are "black boxes" out there like pac tr-7 and tm's bypass circuit...but how hard is it to get around this btw? it's illegal in all 50 states to have video within site of driver while car is in motion..but..just wondering..

potroast Posted September 6, 2004 Report Share Posted September 6, 2004 usually you can just short it to ground to bypass.however, our 850's do have a brake light. Get in your car, start it, and then pull the brake up and down. There's a red "Park Brake" light in the cluster on the right hand side.You can get the wire either behind the cluster, or at the actual parking brake.Personally I would just bypass it. Bypassed or not the law is in effect, and I'm not stupid enough to drive with a movie distracting me... So I feel I can control myself enough to not be using it :rolleyes: Link to comment Share on other sites More sharing options...
JehovArob Posted September 6, 2004 Report Share Posted September 6, 2004 Ouch...According to this wiring diagram is has a yellow wire, which there are a bunch of.So, best bet, if you're going to use this wire, would be to find it at the switch.

steve s Posted September 6, 2004 Author Report Share Posted September 6, 2004 wait. are we talking about the emergency handbrake or the P as in transmission P brake? Link to comment Share on other sites More sharing options...
JehovArob Posted September 6, 2004 Report Share Posted September 6, 2004 Heh, good point.They were talking about the hand brake, so I did as well.Guess parking brake would be more convienent, no?In that case, this looks like the right diagram, showing green to be the wire you want.

Lewis Posted September 12, 2004 Report Share Posted September 12, 2004 Steve S, I just installed myself a IVA-D300 alpine video display. If your 850 has the same setup for the parking brake than mine (850 '93) then you take the center console off, not completely. Just unscrew it, pull the back end up (where there's the armrest) untill you can see under. Then you'll see the switch at the end of the parking brake. The wire is yellow, and it's the only one going to the parking brake so it's easy to see. Just cut it before the p-br. switch, solder a wire to it going to your new switch, then solder the original yellow wire to the other end of the switch, and voilà. I did it in 30 minutes. The longest part is to unscrew the center console : 1. Under the parking brake there's a plastic piece that you can pull out. It lets the parking brake go threw the hole when you pull the console up.2. Open the armrest, take the plastic cover by pulling on it (it goes off easily), you'll see two torx screws, unscrew them.3. Under the radio, at the front end of the console, under the ash tray, at the right of the lighter plug, where you can put coins, pull on the coin thing, there's one screw. At the lighter plug, there's another one. Unplug the three wires going to the lighter plug (two for the plug and one for the plug light). Then you can pull up the whole tray up and then towards you, I had to pull hard on it but didn't brake anything. 4. Under the tray, you see a bunch of wires and two big connectors, the console is screwed in front of those connectors with two torx pointing to the floor. They're on a kind of plastic bridge. Take'em off, those where the last ones to unscrew.5. Pull the console up, the p-brake might get stuck, it's a bunch of wires getting stuck under the p-brake when you pull it up, just push them out of the way towards the front of the p-brake. Then you'll be able to pull the console up and get to the p-brake wire.It's very easy and doesn't take time. I screw the switch on the plastic cover under the p-brake, so it's hidden under the p-brake. This way, when I have my hand on the p-brake, I just extend a finger and flip the switch.Oh yeah, it's illegal so when you'll get arrested, put the switch on the off position... and hide it, just in case.yellow wire------------new switch--------yellow wire--------p-brake switch----ground(that's one complicated diagram!!) ) Link to comment Share on other sites More sharing options...
