Loving the transformation!
Those DRL switchback LEDs you've got are expensive, more than twice the price I paid on eBay when I got them for my RX300. Anyway, if you want the wiring diagram for the switching relays just let me know.
Oh, and make sure that you bolt those resistors to a good metal base to act as a heatsink because they do run hot. I used some MX2 thermal paste on the bottom of them so that there's a very good thermal transfer. Alternatively, you could buy a flasher unit specifically for LEDs like this one and do away with those resistors completely.
