This may be covered somewhere else and is so, if someone could direct me that way.
I recently purchased a headlight conversion kit with all the new relays, but I mistakenly ordered a four liight kit and not the two light kit, can I convert this to a two light system?

And if so, what do I need to do? This is for 1972 C10

Sure, just use the 3-prong connectors which are intended for high-low beam lamps. Ignore the 2-prong, high beam only connectors..... they won't be used.

Thanks guys for your input, finished this today, was a little confused for a few minutes as this kit came with the sockets for the lights, but also had a male three prong plug, after a few minutes of studying, realized this plugs into one of the old light sockets, made for a very simple hook-up, no splicing of wires, everything works great.
