I just installed LED headlights this past week. After a fair amount of research, I used the "Yun method", as documented in this forum, to ground the foglamp relay - IMHO the easiest and most foolproof way. There is no need to cut any wires and no need to guess at anything - the foglamp relay is under the passenger side hush panel, furthest towards the passenger door. It is easy to remove and replace the relay - if you want to double check that you have the right one, just remove the relay and the foglamps will not work any more. The pin to be grounded is the one furthest away from the passenger door, i.e. closest to the next adjacent relay. As has been documented, a double bend in that pin allows for the circuit to be broken (and the pin appropriately grounded) while allowing the relay to be re-installed in place.

I used a replacement auto relay (they're all identical) so can easily swap back the original for a 100% return to stock.

This is the second time I owe Yun a big thanks!
