Ok, i have a Viper 5900 with remote start. Bascicullly, what i wanna attempt is to wire one of the aux wires from the 5900 to the moon roof (pin 9, black, open control wire) to open the moon roof.

Now the black wire to the moon roof, pin 9, is at 11 Volts. With i press open, circuit is cut to 0 volts.


So my wondering is, and this is where i need your help is, How do i wire a relay to cut the voltage to that wire with the security sends the 200miliamp signal to the relay and to fool the moon roof to open?

 

Ok this is what i think i need.

Ok.

I believe i'm gonna need a 5 pin relay.

I'll have

Pin 86 wired to the Aux Wire on the security system.

Pin 85 Connected to ground.

Pin 30 connected to input Moonroof control wire from dome.

Pin 87a connected to Output to moonroof open control wire

Pin 87 Connected to nothing.


So simple as this,

When Coil is powered from the Aux wire, the switch will switched to 87 with no volt output and fool the moon roof to open.

When coil is not powered, 87a will be powered and when the moon roof switch is pressed, 30 to 87a won't be powered.

Running to Checkers now to buy a 5 pin relay, Wish me luck!

 

this website that i used for doin shaved car doors has the schematics for that same very project your tryin out.... its called 12volt.com they have alot of relay setups and forums that talk about the same stuff your doin,,, give it a try

 

I have been working on this project for a year now and havent found what i am looking for. the webpage homedude suggested doesnt have crap on it. it all says coming soon

 

Back from the grave for this thread

I believe the relay wirings he posted above are correct. Ryfly, did that work for you? Seems like it should.

 

IM WORKING ON PUTTING A POST TOGETHER FORE YOU GUYS.

 

while that dude is still putting a post together, i created the answer and it is cake
