disarm viper 5904 by wire/signal

If you've already installed it, try removing the ground wire then reconnecting.Test before boxing up.

you can bench test all you want, the reason alarms act funny when they have power but no ground is because it is installed into a car and connected to other grounded circuits inside of the car. so what happens when you cut the main ground is that the alarm tried to ground itself through other circuits that its connected to. in this case bench testing your theory is not the same as doing it on a fully installed alarm.

We've crossed posts, read it. I agree with you, look at my last line.Test before boxing up.

I think we're back to a DC-DC convertor and a spare remote.Test before boxing up.

yea i just read id. we've been playing post tag... but yea, i know that is what will happen. it may work but it is not good for the alarm or car. ive seen all kinds of strange things happen when you have a bad or broken ground on alarms. ive seen them hold ground on the lock outputs and fry the lock solenoids before as an example of a worst case scenario.

True that's why I thought better of it, your idea works for me, complete control.Test before boxing up.
