Hey guys, I'm trying to get the truck finished up today. I am installing an aftermarket washer pump and I need to know which wires I need to reroute from the original pump. Aftermarket just has red and black.

Thanks, Dan.

Red = 12 V
Black = ground

There is a 2 wire connector on your wiper motor going to pump( blue and yellow-Yellow has 2yellows into one). Pull connector off pump(hard to get off) and connector the 2 wires from new pump to this connector(crimp male spades on too insert into connector). To operate pump just push original button and hold for as long as you want the water to flow--wipers will come on also.
