I was given an aftermarket alarm and would like to install it on my 03 F150. Where can I get like diagram of the trucks wiring.

Or is there someone that can tell me where to hook up for all the alarm connections. It came with instructions but I am a little cautious of cutting into the wires on the truck.

Thanks

 

Check out www.the12volt.com . If they don't have the diagram already listed, you can request one in the forums.
