Based on what has been stated before its easier than running new wiring and taking dash trunk etc apart. but you still have to remove front bumper and wheel well covers to get new lights in and out..

"From hallogen headlight to LCI Xenon (not AHL)
2 - 2
3 - 3
6 - 6
9 - 5
10 - 8
11 - 7
12 - 1

then add extra GND to pin 4

After that take out 2 pins from FRM and join them together into one pin (Y connection)
(pin 4 - A58*2b) and (pin 6 - A58*1B) to FRM pin 41 (A58*2B)"

there's a few other threads on it, so doable and definitely simpler and close to half the cost of going to LED..

Has anyone done this DiY ? I think is the retrofit I need for a pair of Aftermarket LED without AHL.
