Ok, so far as I have read, if your car is on FW1, and built before March 2007, then you will need a Vista DRL harness to have halos as DRL?
Am I correct?
If dealer updates the computer, do I still need the Vista Harness?
I put this in the coding section, as this is a when to code, and not to code question.
Thx in advance for your input.
You need the harness or you can upgrade to the frm2 for about 2x the price and do it the right way
