quick question to those who has installed HIDs on an F4i. i have a black ancd red wire with paddle connector that has to go to my stock headlight plug, my question is, on the stock harness which is positive and which is negative, i cant find any markings, and all i have is a green wire and a light blue wire. which is which? thanks

 

nevermind figured it out

 

Yup yup... on the F4i no matter what circuit you're working with (generally), the solid green wire is always the ground
