Wiring second pump to hobbs switch

[esacteksab]

I've got a hobbs switch and a twin Fore setup. Trying to figure out how to wire the relay.

Wires out of relay are

Black 12v Switch to relay 12v/pos OE wire (chassis side)
Yellow 12v Power to pump 12v/pos OE wire (pump side)
White Ground Chassis Ground
Blue 12v power from batt Power Cable (red)

The hobbs switch is two wires. I'm not certain where they connect to?

Has anyone done this? Off the Fore I have 4 wires, 2 red, 2 black. A pair of red/black are the primary pump that's wired and works as expected. I'm not sure how to wire the remaining red/black pair with the hobbs switch.

Any help would be greatly appreciated!

Thanks!!

Seems easy enough





You can wire the hobbs switch in between 85 ground or 86 12v acc/ign wire to complete the circuit. The switch is open until it sees the set amount of boost and then it closes the circuit to energize the relay.

The red wire from the pump will connect to the yellow wire on your relay and the black wire will be grounded to the chassis.

Hope this helps and doesn't confuse you. I'm not good at explaining stuff like this.
