The Best Way to Wire a 9-Way Vehicle Connector to a Trailer Side 9-Way Connector

Question:

I see the colors and the numbers for the pins that you provided but is that looking at the holes from the front of the plug or from the back where the wires would attach to?

The numbers that are given behind the colors for wiring chart of this Pollak 9-Pole # PK12907 are the gauge wire that is recommended you use for that circuit.

If you need the matching 9-way trailer connector you would want a Pollak 9-Pole, Round Pin Trailer Connector # PK12906.

There is not a standard wiring for 9-ways, you will need to wire the # PK12907 by function to the corresponding trailer 9-way connector.

I attached an FAQ on trailer wiring that you might find helpful also.

Unfortunately, we do not have 9 wire cable available. The only thing you could do if your having trouble finding some is take a 7 pole harness and wire two wires in with the others.
