2006 Chevy Express 3500: a wiring diagram..Van..connector..trailer

This answer was rated:

Need a wiring diagram for 2006 Chevy Express 3500 Van w 4.8 L V-8 engine, or what wires I need to tap for 7-connector trailer plug (L & R turn, brake,
running, etc.)

Thanks,

Charlie

Welcome Charlie. IF your truck does not have a trailer plug then I suggest you go to Hoppy and get the powered inverter. This will have you run a powered wire to the box, then it will use the left, right, reverse and park lights on the vehicle as an input and will then use the power wire to run the trailer lights. This way your vehicle lights and wiring are protected.

Think I have a trailer plug, but it is a four-wire plug at the top of the rear doors. Also, what is Hoppy?

Thanks,

Charlie

Hoppy is the brand of trailer plug.
