Anyway, the driver's side is virtually impossible to mount properly, unless you extend the wires all the way to the back, and even then it's iffy.
If you have the slim ballasts, I mounted it LITERALLY underneath the headlight.

If you guys got XenonDepot stuff, I'm to assume that you have their ultra slim ballasts? Be careful, those have an odd history of failure rates.
