Question

Answer
Without knowing what year, make and model of truck you have I can only suggest you take the radio out and look to see what color wires are not part of the original connector for the factory radio.  If you have cut a wire that doesn't appear to be in the factory harness for the radio, it was likely for something else.  Look on the bright side, you won't be putting very many miles on the odometer!  If you give me more info I may be able to help you more.
Hope this helps
