Heater wires

Rear heater. I traced these back to the switch but I’m still confused. Low/High. Two white and one red. Are all 3 + ?

Test them with a digital multimeter. Meter black to ground, red to each wire while switching with the switch. It will tell you which is +. Also check different combinations of wire to wire.
Or just look at a wiring diagram.

I was going to test them but I didnít bring the ignition key. Just hoping someone has repurposed one of these. I want to repurpose the switch for my water pump and wire it in to the solar.

Mine grounded to chassis and only had two wires, low + and high +. Not a lot of other things to do in a heater box.
