I am sure the answers to my question are already some where in thread but here goes. Are 72 C20 is driving me bananas. The side marker lights in the front fenders don't work there is power on the brown wire side of the pigtail. So I thought okay it's a ground issue so I un taped the wiring down down the as far as I could to discover the ground wire for the pigtail is factory soldiered to the blue turn signal wire for the marker light in the front bumper. As I have discovered from reading on here the side marker lights are supposed to flash on 71 and 72 pickups when the turn signal is on. So my question is where is the ground supposed to come from for the light to work?
