I have a 2013 F150 Screw and I'm installing puddle lights from thedoubleaa.com. I have one installed already but haven't hooked power to it yet. Anyone know which power wire to tap into that is in the door? Thanks

Find the one that's for the lights in the door and tap into that.

 

generally the purple wire in harness going to harness is positive and ground is to chasis.

 

I hope the OP already found one, the post is almost a year old!
