Great upgrade! Post your opinion after the install. Good luck!
I installed the upgrade on saturday......though I didnt have a chance to test on the road at night yet, I did test in the garage in the dark and yeah its BRIGHT baby. I tried using my cell phone light meter app...I measured about 15-1600 lux before and (if i did it right) 2500-ish lux after....IF I did it right....
I ended up mounting the relays on the radiator side , front edge of the battery tray.....underneath, and used two rivets/washers to secure it.
For my battery it ended up a perfect spot....and the two main fused ended up in front of the battery where I can get to them easily.
I suppose because I installed there versus on the REAR edge of the tray, the harness leading to the alternator was a little short....so I am telegraph-wiring between the tray and the firewall a little. Not horrible but wish I had just a few more inches of cable (no jokes please....LOL)
If I had installed the relays on the BACK edge of the battery the fuses would have ended up there as well, and I prefer them in the front for accessibility.
But everything went in easy.....just about 2 hours as has been said. I spent added time tweaking other stuff as I went along....
Its an extremely high quality kit....heavy wire loom covering, relays look great, etc. Well thought out and engineered as far as I can see.
Cant wait till I drive at night to see what the difference is !
