Does the Talon have the factory amp under the seat? Did you insulate all the unused wires left over from the install. Maybe the illumination switch wire is shorted out.

Obviously check all fuses first and go from there. The illumation wire will be neutal and go to positive when you turn on your parking lights if you want to test for the wire. Sorry, cant remember the color off the top of my head.

I'll see what information I have at work and try to post again
