Re: Mystery plug

I'm thinking that's for your underdash courtesy lights. See how their tied into the interior cab light harness.

Re: Mystery plug

Aren't they the colors of the courtesy lights, dome and door opening?

Re: Mystery plug

I believe the door plugs just use the white wire, and the yellow goes to the two lights
