Re: 2015 halogen to HID's
The HID Fogs will work fine without using the relay harnesses. The bulbs only draw 35 watts and the initial surge is less than 4.5 amps...
The relay harnesses are substantial, and running any load directly from the battery will help to ensure less (potential) voltage drop, but in this case it more than doubles the work involved to perform the installation.
In my case, I bought a bunch of fender rivets/rivet tool and push pins, got a length of wiring loom to make everything look pretty, then opted to try the installation via direct plug-in once I realized I could do it just by pulling off the front air dam (7 quarter-turn fasteners).
It's working so far. If I run into issues down the road, I still have the relay harnesses...
If we knew what is was we were doing, it would not be called research, would it? Albert Einstein
