I would like to put a viper 3002 alarm on a 1971 Cadillac Sedan Deville. Can someone supply me with an alarm wiring diagram for this car? Thank You

That car should be very easy. You can even use your old school test light on this one

pull up a 1984 Sedan de Ville diagram and use as a basis. If it has power locks I would imagine they might be reverse polarity

I still need help with the installation. It blows a fuse to the door lock harness when arm/disarm the alarm. I can crank it while the alarm is sounding. Its only has 3 wires on the lock switch, one is hot all the time and others become hot when you lock/unlock the doors.

How did you hook up the dooor locks? Reverse Polarity right? This mean you cut both the lock and unlock wires in half. This car may be mastered from the passenger door lock switch

Starter kill wire should be yellow or violet maybe key side and starter side wires need to be switched around

Well to be honest I tapped into the lock/unlock wires and it just blew a fuse. So I started to wire it up Revering Polarity, I cut the wires on the driver side and the locks still worked at the switch on the driver. I walked around to passenger side and press the lock/unlock button and they worked on that side. Seems cutting the wires to lock/unlock on the driver side only seperated the lock system. Driver side and Passenger side. I cut the green wire which locks and I cut the black wire which unlocks on the driver side.

Ok I made some progress, I wired the door harness for reverse polarity and it does work ,but only on the passenger side. How do I get the driver side to work?
