    The fuse panel looks like a great way to eliminate the old ceramic fuses.

    It looks 3D printed, how do they fair with heat?

    The headlight looms, do they piggyback off the original headlight loom for switching & have their own 12V hookup to the battery?

    Had an eye on your stuff for a long while now, really nice stuff!

  • Thanks, Julian.

    Fuse panel is not 3d. Very nice part it is! Installed the first one in my wagon, which has half a dozen extra circuits plumbed through it. Been in there for two months, no problems, and no gymnastics to twirl fuses while one is driving (which would REALLY be a feat with RHD!). Have already installed five here at the shop for customers. Wonderful upgrade.

    Headlight harnesses have two fuse holders, one for low and one for high beam (where applicable) with separate relays and supply lines. Depending on the car, I'll get a BIG female spade lug and grab one of the "end" terminals in the junction box for both leads. I have had people tell me they go right to the battery, using the fuel pump attachment point on the positive cable. No question you can't get more direct than that. The harnesses use the original, left headlight plug (single or low beam) to control switching. I say "where applicable" on the high/low, because we've already made at least half a dozen custom kits for single rounds/squares and a couple of really wild LED setups too.

    Please feel free to e-mail me directly from the website if need be.

    Thanks again,


  • I've done that headlight bypass too in my 164 and 740, and it does make a difference even after replacing the bulbs with better quality ones.
