Wiper motor housing hot.. 70' 2 speed

Hello,
Kinda hard to understand what you are trying to show us in your picture.
Are the two wires from the ballast resistor?
You should have a ground strap that goes from the housing to one of the posts that attach the motor to the car body like in this picture.
Also can you show how you are checking the "Hot"?
if you don't have the ground you will need to install one.
let us know what you are trying to depict in your picture.
Thanks.
