Question:

https://www.etrailer.com/question-150760.html I am referencing the above question. I would like to run a 12 volt water transfer pump from my trailer connector on my 2015 GMC Sierra 1500... Im trying to set up an easy way to pump water out of a 7 gallon tank into my water tank on my travel trailer. Is this feasible?

Expert Reply:

There is a 12 volt accessory pin on standard trailer wiring 7-ways. It's the pin in the 1:00 position. This circuit does not typically carry a high amperage rating but it should work well for a smaller water pump.

You could use the following if you were trying to make an adapter that would plug right into the 7-way:

7-way plug # A7WCB
10 gauge wire # 10-2-1
2 pole flat wiring # HM47965
butt connectors # DW05745-5

The picture shows it wiring to a fuel pump but you'd just need to substitute that for the water pump.
