First I apologize for the bad sketch. Now the sketch shows how my wires were hooked up as I took the light off. Now, the Grande wiring sketch shows , looking down, blue left , green center, right black. The base shows GST, ( photo) I’m assuming G is ground. My thinking is to hook them up as I took them off. The wire harness is original, no sketchy wire work. Any thoughts. BT W. This is another basket case , and it was in pieces , so engine wasn’t in a box .
