LOOK AT THE BALLASTS - YOU'LL HAVE TWO BLUE, TWO RED AND TWO YELLOW plus a white and a black.
Look at the sockets - there'll be four holes on each socket (quick wire) one pair for one side, one pair for the other side.
lamp one - one side - insert one blue into one pair, the other blue into the next pair. Next socket - one red into one pair, other red into the other pair. Opposite end - socket 1, hole pair 1 - one yellow and a jumper. hole pair 2 - other yellow and a jumper. socket 2 - first hole pair - one jumper from socket 1, next hole pair, other jumper from socket 1. The black & white connects to 120 volt circuit. confused? send me an email and I'll send you a drawing - srf12980@localnet.com
