Evening! I did several searches & came up empty. Wanting to add a couple LEDs in the interior that are dimmed with the regular dimming method for dash lights. I’ve metered every damn wire on the radio plug & electric trailer brake module & none of them actually change voltage with the dimmer. Has anyone had any luck finding the source for this function? Thanks!!

 

I think the BCM controls it, but it's confusing.

 

Look for the violet-gray wire.

 

Maybe this will help.

 

Thanks guys!!! 👊🏻
