And yes, you should get the harness if you're running H4s without projectors. Shoot, from what I've read, you should run the harness even with the stock headlights and you'll see a big improvement

Very true on this point. I did the harness first in mine, huge difference in the stock lights. Have the Autopal H4's waiting for some time this weekend to go in.

Just saw the pictures and DANG those things make a world of difference. Now I really can't wait to get my harness in there.

Attach the harness to the existing harness behind the grille working toward the passenger side. . Plug the new harness plug into passenger headlamp. Plug original headlamp plug into receptacle on new harness. Attach the ground for the passenger side just like you did the driver side under a radiator support bolt. Attach relays with provided bracket on the passenger side inner fender. Connect power wires to battery.

It's a rare car that doesn't benefit from a relay harness.
I've got one sitting here ready to go and a pair of Cibie E-codes with some slightly hotter than stock bulbs (ssh) and sadly my wrench time today was on brakes, not headlights. Sadly, can only do so much at one time and brakes are a little more important. Not that much, but a little.
