Kw trucks they have spare power/grounds to tap into exactly where your pointing at.

You had to have tapped into obviously the wrong circuit. Did you try and disconect the wires you tapped into just for shits and giggle to see if your codes would go away?

Their is certain circuits you can not tap into to grab power from. But their still should be spare power/spare you can use??? Look in your fuse panel and see what power and ground is a spare and find that wire/s and use that. You will need to probably add a fuse in your fuse panel

I'm driving a prostar. There are tonnes of places I can tap into. If this isn't a good option then I'll just run a seperate fuse from my panel. I didn't see any harm in the wires I chose, there's a obvious constant, accessory, ground and dimmer. I thought it was cut and dry.

I'm still trying to figure if there wires have anything to do with the engine j1939.
