Anyone have a diagram of the electrical plug underneath rear of 67 GMC? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My left turn signal park light doesn't work. I unplugged the harness at the rear on the frame. With a test light I have power on one of 4 terminals with the park lights on. Would be handy to know what terminal is for what function. Does anyone have a diagram of the terminals and what powers what? Thanks

Thanks but I have all the lights working now. I should have known since I'm the same age as this truck that sometimes it takes a little time to get things working.

This is the wiring harness for the rear of the truck.

The blue arrow points to the switched ground wire for the dome light.
