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!

If you're going to use a separate switch for the pump, look for a momentary-on switch. That way, it only pumps while you hold the button/toggle and stops when you let go.
