I have a 91 Ford Mustang GT with the power options (locks and windows) with a Viper alarm installed in it when I bought the car off of the previous owner.  I no longer want that system in my car and have no experience with car security and or alarm systems.  Is there any wiring diagrams or etc available to show me a schematic of the wires and hook ups for the system so I am aware of what I am doing when pulling out the old system and installing a new one.

If you have no experience than you should bring it to shop. It will save you lot of headache.

Good luck........
