How to Wire a Shurflo 12V Pump

by K.K. Lowell

Installing or replacing a pump in an RV or boat is a task that is quite manageable for most do-it-yourself people. Parts are available from local RV supply stores, as well as some automotive and large department stores.

Step 1

Mount the ShurFlo pump near the freshwater supply tank.

Step 2

Locate a switch in an easily accessed area. This switch can be as simple as a toggle switch, or a switch mounted in the wall to match the light switches in the RV.

Step 3

Mount a 10-amp auto-resetting circuit breaker near the RV house battery.

Step 4

Run a 14 gauge wire from the circuit breaker to the positive terminal of the house battery.

Step 5

Run a 14 gauge wire from the other circuit breaker terminal to the center terminal of the toggle switch.

Step 6

Connect the other side of the switch to the red wire of the pump with 14 gauge wire.

Step 7

Connect the black wire on the pump to the negative terminal of the house battery.
