Not a whole lot. I bought a harness off eBay for $10. All you really have to do is plug into the 9004 harness, run 12v power and a few grounds and you are good to connect to the ballast.
Looks good! I will post pics of mine this weekend when its a little warmer outside. It's currently in the 20's here and I get all my work done at night so it's too cold for me in the garage.
That side is wired temporarily, and not sealed yet.
The cutoff seems to be pretty good. It's hard to tell though since the wall is only about 3 feet away. Soon as I am able I'll get the car backed up into the driveway and see what the cutoff really looks like. I can safely say it is MUCH brighter than the Silverstar Ultra in the drivers side.
Everything bought from RetroFit. Projector kit, 5k bulbs, and glue. All pretty much plug and play with the exception of cutting off the stock bulb holder on the headlights
Bringing this back from the grave but how is the retrofit working after a year past? Im getting ready to do the same thing and my only question is for ballast. You can buy the wiring kit but where does it plug into? Do you just wire it into the stock fox light harness?
Yes it gets wired into the stock light harness and you have to hook up power and grounds. The wiring is the simple part. I wouldnt recommend the butyl sealant, that stuff leaked like crazy when i used it, i ended up patching it with Right Stuff silicone and have had no leaks.
