I bought a wiring harness for my neon and wired it to my JVC deck, the deck works except that my instrument pannel isn't lighting up, I think I mismatched the wire on the deck that is suppose to be for the dash lighting, all other lights work though including the roof light. I need to know which wire on my deck would be for the illumination for the instrument pannel and deck, since I bought the deck used I don't have the manual, thanks.
