1974 c10 headlight socket 4 to 3 wire?

[jmon12179]

Hi all. Picked up a great 74 c10 to restore on my off time.

I have a headlight out due to the socket and wiring right outside of socket being corroded and messed up. I bought a standard socket which is 3 wire. I went out to the truck and I didnt even notice that it has 4 wires. Red, green, and 2 black. So I figure the 2 black are grounds. How do I make the standard 3 wire work? Splice into 2? Just leave one of the grounds disconnected?

Thanks any help guys. This is a great forum

You are going from a 3 prong plug to a 3 prong plug. The 2 black wires are connected together in the spade of the plug so when you wire the new plug you will have to connect them togerther outside the plug.(providing it is configured the way I described.)
