Installed the Morimoto Elite HID 35W 5000K PNP kit this past weekend and love them thus far. I haven't gotten around to adjusting them yet, but no flashing from oncoming traffic to date. Due to high perch setting, I'm sure I'll need to bring them down a bit. I routed from one headlight to the other following existing OEM cable routing atop radiator. Used existing grounding point for driver side, but due to battery tray I was not able to get to the passenger side ground. Therefore, I just used a local existing structural screw below headlight housing. Fuse ended up being near existing fuses while the relay ended up being between battery tray and ground cable bundle. Used some zip ties to bundle wires with existing wire bundles. The ballasts were mounted atop rectangular tube below headlight housings. This area should be safer from road/trail debris, but still accessible from below without removing headlight housing again. I didn't want to drill any new holes, so I simply used double sided cushioned tap, electrical tape and zip ties.
I'll post some pics soon. I'll also try to take some pics of the actual lights in action. Thanks again for everyone's help and tips. LEDs for the tag, backup, puddle, and cargo lights next.
