Good deal!I installed the harness today. I separated the leads for the high and low beam circuits, removed the included fuse holders, and installed each lead to an individual terminal on a Blue Sea fuse block.
I didn't have a chance to take it out tonight, but I imagine that even with the included bulbs, the harness will benefit with better light than just running the housings and bulbs without the harness. I'll post back with my impressions later this week when I get a chance to get out after dark.
Could you tell what gauge wire it was since you modified the harness? I almost cut into the harness just to confirm the wire gauge but I didn't.
