Didn't think of that, thank you very much.

Do you know what color wire is the constant on? Used a voltmeter and hit each pin with the truck off and did not find a constant on.

Are you sure that the 7 pin has a constant on and not a switched 12V lead?

I know on GM trucks the constant power is fused and the fuse is not installed from the factory. You have to install it yourself.

just came across this for GMs:
How to Hook Up the Constant 12v Power for 7pin Trailer Plug : How-To Articles

Is there something like this on a SD? The top right pin is not giving me a reading with the voltmeter with the truck off... haven't tried it on
