hey guys, when i bought my cutlass we had to boost it, the radio was on & turned all the way up, so i dove in the car and just turned it down all the way, i now have an alternater and battery in the car and itll crank, i pulled out the stock sterio and started wireing in an aftermarket deck, have all the speakers wired up, but can't seem to find an active power and ground, i tracked down a wireing diagram and orange is power and it dosnt say for ground, but im assuming it's either black or brown, the extra wires i have are 2 orange, 1 black, 2 extra grey wires, and 1 other for ign, but since i put in the alternator and battery i havent been able to get the stock sterio on, i assumed that the radio was pooched , i've checked fuses and to see if the car gets power, it gets power and fuses are fine, so i guess i have 2 questions, on my deck i have a yellow and a black for power and ground, which orange is going to be a power source, and also what colour should i ground it to, or should i ground it to the dash chassis? i've messed around with each connection and tried to combonate the cords differently each time unhooking the batt & rewireing, hooking batt up & test, but it dosnt seem to be getting any power at all.
