Ok, so I'm getting a Viper 791XV soon, and I'll be installing it myself. I've done a few, but not on a Cav. On my DEI sheet, it says I need the 555LW for the bypass, but also the 457GW as a "combo interface"? It's noted "Can use the 1700G or 457GW to bypass the Passlock II, but it will not control the door logs on this model year." Does that just mean I need the 555LW and that's it? that's what I'm thinking.
Just wanna confirm. thx
Another question as well... since there isn't a domelight supervision wire, can I use a relay to use the 200mah negative trigger, so that when I unlock the car the dome light comes on? I know the dome light it a negative trigger as well.... and this is currently how I have my cathodes hooked up.
use the door triggers and diode isolate them.
I know that part for the door triggers... ah well, it was just an idea I had. maybe it'll work, maybe it won't.
Get the 555lw, use the lock/unlock motors off the driver's kick panel, and use relays to reverse polarity.
the 791xv has a built in polarity selector. I know both lock/unlock's are positive triggers.
My question was when the alarm goes off, what can I do to make the dome light (interior lights) turn on (like factory)? or will it do it automatically? In other cars we hooked up the Dome Supervision wire (negative trigger, 200mah through a relay). The Cav's don't have a dome supervision wire built in.
You could have it pulse the door trigger so it would turn the dome light on.
That's true, then have it stop if I re-arm it. I'll play with it.
Just use the 555L, your only gonna use the following wires
RED - 12V
PINK - IGN
Blue/Black - Status input
Black - Passlock Ground input
Black/Yellow - R-Code - BCM SIDE
Yellow - R-Code - Keyside
Don't use the BLACK/WHITE or the VOILET wires.
I had my Alarm installed YEARS ago when I 1st got my car, and when I UNARM/UNLOCK the doors the dome light comes on, I think the cars that came with Keyless Entry will do this automatically. Not sure but I think so. You could hook it up and just try it to see if it works. Also when I arm my alarm the dome light goes through a small delay and then turns off, if I do not arm the alram the delay is longer for sure. My car is in storage as of now so I can't tell you what he hooked up. But like I said you could just hook up the locks and see if it automatically works.
Also on my 2003 when I lock/unlock my doors with my Compustar Remote Starter the dome light turns on/off and there was no extra wiring there.
