Once again sorry to ask this here. I know where to hook up the green wire that goes to a blue wire in the EM1 engine bay and the black of course is ground. Where does the red (12vsource) go to in a EM1 engine bay.

 

12v source will go to a key on power source like a splice into your radio power source or maybe your windshield wipers.

 

red should go under the dash in the fuse box, check for a free spot that is 12volts, and you gotta make sure that its the one that only comes on with the lights

 

easiest way to do it is, take a volt meter and test all the vacant spots with the lights on, and turn em off when ur testing, the one that stops reading with the lights off but works when there on is the one u need
