Answer 2

i would have the ungo alarm removed completely and the trucks wiring put back to stock. it sounds like the wiring involving your dimmer switch and the parking light may be mixed up. take it to a pro and have the alarm removed. them make sure all you fuses are good.good luck!

Answer 3

you have to pull your radio out and there is an orange wire its you illumination wire and you have to disconnect it from the radio or the alarm which ever it is hooked to
