My bad, I thought 300 ohms was in open position (lights off) and zero ohms when it is closed (lights on). What is confusing me is when he talks about moving the lever, which way is he moving it.

if he moves it with brake pedal it will close it.
If he has it off the truck and moves it, it would open it.

Sorry, trying to figure out so I understand.

Shaffer, can you please describe how you are testing and which way you are moving the lever/switch? Some of us (me) aren’t smart but like to learn.
