How to Install the Pollak HD 7-Pole Round Pin Connector

Today, on our trailer we'll be installing the Pollak heavy duty, seven pull, round pin connector with Cable Guard, part number PK11702. Now, we already have our seven way wiring coming off our junction box. As well as, already having stripped some wire back that we'll be connecting our new seven-pin connector to. To begin with, we'll need to take the small set screw, as well as the relief strain screw loose to remove the center portion of the seven pin connector. We'll go ahead and pull out the center portion, as this is where we'll be connecting our wires. We're going to go ahead and show you a comparison of what was on the customer's trailer already. We'll be rewiring it exactly how the customer had it.

Now, depending on your truck's wiring your wiring may be in a little bit different order or the colors will go to some different locations on the back of the seven way. You'll want to test your vehicle using a test light, so you know which pin does which function. We'll go ahead and match each wire color for color with how the customer's trailer was already wired. Now, you will notice that the new plug we'll be adding a yellow wire in, as the old wiring on the customer's trailer only had a six wire plug and this new plug is a seven wire plug. Now, our extra yellow wire will actually go in the center, in between the green and the red wire, and just below the blue wire, which, is actually the very center wire on this plug. Now, that we have the wires connected to the new plug let's go over what our functions do on our particular trailer. The white wire is the ground wire.

The blue wire is the electric brake wire. The black wire is the 12 volt hot wire. The red wire is the left turn and stop. The brown wire is the right turn and stop. The green wire is the taillights, or the running lights and the yellow wire is the auxiliary. Now, we're ready to put the center portion of the plug back into the housing.

We'll simply pull the center portion back down into the housing, lining up the set screw hole. Next, we'll put the set screw back into place and then, we'll tighten down the cable release screw that helps keep the cable in place. With that done, that's all there is to it to installing the new Pollak heavy duty, seven pull, round pin connector with Cable Guard, part number PK11702. .
