There are 3 wires.....I assume the black is ground..... Where would I hook the other two......to my coil negative side (green?) and the other to power (red?) in order for the light to work? Thanks.. 1969 Buick Sportwagon 455 Stage 1 Ram Air SOLD Nationwise Auto Parts Alumni 1982-1984 Now 1972 El Camino, original 402

But I would find out 4 sure as you dont want to fry it, might google it live every 24 hour block of time like it's your last day on earth
