Well, I hooked up the keyless entry to my vehicle...1991 Ford Explorer, using the following...
http://www.the12volt.com/doorlocks/page3.asp#5w

When I plugged the vehicle's battery back in, the cab filled with smoke (a lot of it.) I looked and noticed that the wire I had running from the constant 12 V wire (yellow wire in ignition switch harness) to terminals 87 on both relays had burned through the insulation and the insulation of several other wires. The relays are hooked up correctly...Pins 87a and 30 are, no current = motor / current = switch. Can this occur because I used too small of a gauge of wire to make the connections? The wires from the brain's harness are not very thick, but the wire I used to power the relays is pretty thick. Please Help!
 






sounds like your wire is not fused properly, and is shorting to ground (maybe frayed or improperly insulated splices) use a smaller fuse (125% of the expected maximum current) and make sure all of the connections are insulated.
