hobbs switch wiring

[gnbeginer]

I bought a double pumper a lil while back and it included wiring but no instructions of how to hook it up. Could someone enlighten me on the best way to hook it up using a hobbs switch?

TIA

Run power and ground to the switch then put a T in a vacuum hose and run to the switch

I assume you got relays w/ the pump harness. So, use the Hobbs power to trigger the relay for the 2nd pump.

All I got with mine was a hacked together wire to run to back of car and a hobbs switch. I do have a relay that i can use if need be.
