@Gretsch If you want to get rid of that Koito harness, I would love to dissect it. I'll gladly pay shipping. The other stuff looks nice too, but I'd love to come up with an inexpensive solution to pair with the inexpensive Koito kit.
If you can figure out how to make this work then its yours. I did cut the trigger plug that goes to the factory headlight plug off the harness. I used the other unused factory plug as a trigger for my Hella Black Magic aux lights. I had been wedging a spade connector into the factory plug to run the lights with the headlights but the connection was not very secure and thought using the male plug that comes with the Koito harness would be a more secure fit for the trigger wire. Wires are color coded so you can still see what goes to what. I'll PM you with details/pictures. Thanks.
