I’m going to install a front map light, thanks to all the post by people who have already done this project. My light came with the three wire plug, red, black and yellow. I will tap the black and red into the middle dome light, but for the map light function I need a 12 V source,. I don’t want to overcharge any circuit. Please advise on how to complete this project. Where should I tap the yelllow wire for ACC when car is on?

 

 

use the original dome light colors as a reference
