ok there is 2 small panels on each side of the deck carefully remove them with a small flat head screwdriver. underneath, you will see two small holes on each side. take 4 thin long rods and put them in these holes and push them outwards(left and right) this will release the locks on each side and the deck will slide forward. Here is the wiring diagram:
Direct : Blue/Red St
Acc : Blue/ White St.
ILL : Red/ Black St.
Ground : that MASSIVE black wire cant get a better ground!!
Front right speaker : Blue/Red St (+) Blue/Yellow St. (-)
Front left speaker : Blue (+) Blue/White St. (-)
Rear Left (by the deck) Pink/Blue St. (+) Grey/ Blue St. (-)
Rear Right (by the deck) Grey/Red St(+) Grey (-)
just do your normal deck testing and u should be ok.
