I'm adding washer fluid pump to my '72. I got a pump and switch. I want to make sure I'm wiring it correctly:
1. Negative on pump goes to ground somewhere on bare metal on car. 2. Positive on pump goes to "LOAD" tab on switch. 3. "EARTH" on switch goes to ground somewhere on bare metal on car. 4. "LOAD" on switch goes to + on pump. 5. "SUPPLY" on switch goes to fuse (#8 or #10, I think), which supplies the power. Is this correct? I got the switch at Radio Shack. It's a "push-to-work" and a light on the switch goes on. It needs to be pushed again to shut it off. I got the pump at Pelican. Thanks! |

The negative side of the pump should go through the switch to ground. This way if any of the switch wires accidentally are shorted to ground, you won't blow a fuse. Also as SirAndy mentioned, the switch should be momentary ON switch, not latching as described. |
