just a heads up, the dim to off feature works great with LEDs also...i just added two lengthwise rows of white leds to my ceiling and 86'd the two factory lights, hooked the new ones up to the factory wiring, works great!
Do you think that you'd be able to post up some pictures of the lighting you have installed in your Promaster? Surprised at how cheap the LEDs were for you. Is that the regular price or did you get a discount because you are in the industry?
Sorry for the year old bump. I installed some LED light as well in my promaster. They worked fine, then nothing. I have scoured the owners manual and internet for the fuse location for the cargo lights with no luck. Anyone give me a hand??
