How to Install a Wiring Harness for a Trailer on a 2008 Chevrolet Silverado 1500


Today we are going to install part number PK11916 from Tow Ready, and we are going to install this wiring part on our 2008 Chevrolet Silverado pickup. Basically, what this part does is it puts a 7-pole end on the back of your pickup, replacing the factory blank right here. Basically, what you are going to do is take this plate here and twist it sideways until a key comes out. And you pull out the blank and the wire harness right here. Undo the wire harness by just pushing down this pin right here, and it comes right apart.

And then, take your new part and just reverse the procedure. You simply put it back together, make sure it snaps into place and then just reinstall it. And it clicks right in position and you are instantly done. As you can see here, this actually replicates the actual factory wiring harness. And that finishes our install of part number 20047 from Tow Ready.

On the factory trailer plug outlet. Is the positive terminal hot all the time and is it fused? When I test mine no voltage is present yet all the lighting works fine.

There is a connection that is needed to be made up in the engine bay on some models. There are two unconnected wires up in the bay by the power distribution bock. They make the connections for the brake controller output and 12V hot lead. I have added a link to a brake controller video where we show how to connect these two wires. Skip to about the 3:30 mark in the video linked below.
