How to Power Small 12V Air Compressor Using Trailer Connector

Question

Question:

My truck does not have a 12V access in the rear of the bed. I have a Viair compressor that I would like to use to add air to lift shocks and/or truck/RV tires. Can I use my 7-pin or 4-pin connectors at the back of the truck for this? If so, how do I connect it up?

We do indeed have an adapter that will convert your 7-way to a 12V power outlet. You'll need part # PK11896. Or if you'd prefer something a bit more permanent, you could install something like # DG6112VP in the inside wall of the truck bed and simply tap it into that 12 volt feed to the trailer connector.
