Black Wire with Insulated Male Spade Terminal = Black Wire/Green Stripe or Blue Wire/Green Stripe (DRIVER SIDE HALO WIRE)
After those 3 changes the halos work as DRL.
Mine is 3/07 build. . . . could I have coded these instead of the harness as well?
I don't think you could have. Your vehicle should have an FRM1 if I am not mistaken, in which case you need the harness or FRM2.
I installed the LCI halogens today with the harness and it all worked great!
