viper 5704 on 2003 cavalier

you could but what if you remote start the car when the alarm is disarmed? using the ground when running is the most fool proof way to fix your problem. the radio will turn on when you take over the car which definitely puts you in range of the pioneer.

Correct wiring after the above posts. GWR to 85 via a 1N4004 diode. Ignition to 86. ACC from switch to radio 87a To radio 30. Second 1N4004 across 85 and 86, band side to 86. Both diodes are mandatory. If the above doesn't work, 12V+ constant to 86 via a 2 amp fuse.

this is true, but i would never remote start the car with the alarm disarmed. its always either parked on the street near my house or in the parking lot at work. where does the gwr wire come from?

well the other downside of using the ground when armed is that the relay would be active the whole time your alarm is armed. i like to keep relays off whenever possible because they do draw some current and if you leave it sitting long enough it will kill your battery. my way the relay will only be on during remote start when the car is running. the GWR comes from the remote starter, on a viper alarm its called the status output. your bypass should also be hooked to this wire

ok, in the wiring for the viper i also see a 2nd status/rear defogger output. i could use that as well correct? as far as finding the diodes? what type of store would carry something like that? or would i be better off ordering online ?

H2/3 or H2/9 although the second one should be used for the by-pass. Radio shack. You should already have used H2/9 for your by-pass.

yep i have h2/9 for the bypass. im gonna try radioshack for the diodes. thanks a lot for the help

ok got everything i need. as far as hooking up the ignition wire, should i use the actual pink wire in the ignition harness or can i use the ignition 1 output wire h2/10 from the viper

it doesnt really matter if you use the factory ignition wire or the output of the viper because it is all tied together anyway.

Either join to H3/1 as detailed above (terminal 86) Then H2/10 to 85 using the diode. What was wrong with using the GWR 2nd at H2/3? I think your causing yourself lots of problems by going over your level of competence.
