I didn’t know how to install a water pump so I went to see the local RV repairman last week. In my estimation, he’s been doing this for over a hundred years and stopped caring about customer service in the seventies.
When I asked him how to hook up the wiring, he barked at me in an irritated voice while gesturing violently at the water pump “red is red and black is black”!
Well, I made this picture for him to show him what the wiring in my RV looks like to me. No, he hasn’t seen it nor will he ever. 🙂
