I have a 2001 Chevy Silverado. I am trying to hook up to a trailer that has a 4 prong plug. The truck has 6 wires coming out underneath. How do these go together?

They make a converter that plugs directly into your 6-pin connector that has the 4-prongs on the backside of it. Just plug in the converter, and you're ready to go!

I use one of those converters on my Expedition. Nice thing is, that if you need to tow your boat with someone elses truck which has a 4-wire plug.... you simply unplug the converter and you're good to go with your old 4-wire plug.

Most Chevy trucks come from the factory wired for a seven wire connector , you need to count the center conductor. Some places won't let you return electrical items so be sure that you have a match with your adaptor....Jack

My 2004 Avalanche came with one of those, so you know you can order one from your dealer. But $35 ???

You can probably find it a lot cheaper at a local parts store.

Make that $18. Much more reasonable. But you can sill find it cheaper.

I agree with Bulldog.
Most vehicles these days come with a seven prong connector, or maybe even 4 prong. But six would be too weird these days.
My 1994 Jeep came standard with the 7 prong when you ordered the tow package.
My 2004 Ford Truck came with both the 7 prong and the 4 prong mounted right alongside the each other... I believe all Ford trucks have come equipped this way for several years now. No adapter really needed unless of course you get one of those weird old 6 prong connectors on a borrowed trailer.
My advice....
Change your truck or automobile to the STANDARD 7 prong connector.
You can always use the 7 to 4 prong adapter for about $8 at Wal-Mart...
