RV Towing Information

RV 7 Pin Connector between Tow Vehicle and Towable RV

While looking at the hitch of the fifth wheel, you might notice a really thick rubbery connector that goes between your tow vehicle and the fifth wheel. 

Most of the time these modern days, this connector is a 7 pin connector ( there can be others, but I don’t think I’ll discuss them here ) that connects controls on your tow vehicle to your RV.

You cannot tow an RV safely ( unless you are only going 10 feet on perfectly level ground across your yard or something ) without this connector connected and working. At a minimum, when you are just connected you should do the following things :

• Check the running lights
• Check the left and right signals
• Check the brake lights
• Do a mini-brake test ( using your controller ) to make sure brakes are working
• Do a backup light test.

By doing these small things, you are being much safer. Don’t just connect and go. OK?

These signals on the connector are ( not in any order ) :

1. Left ( stop & turn ) signal
2. Right ( stop & turn ) signal
3. back up lights
4. running lights
5. brake signals
6. power
7. ground

I’ve found a GREAT wiring diagram here.
