Very interesting cord; I guess it was time for someone to come out with this quick connect. Should work on an H3, but can't say for sure, and evidently they can't either. I guess for someone who does not want to remove the A-pillar molding, it would be the way to go, and the price of a 6" cord (without shipping), is not bad. However, if you have butt end connectors, the price is zero.
On a Vette, I might have opted for that cord, since running the wire under the header molding, pulling that A-pillar molding on the Vette, running the wire under the molding, down around the I/P, under the kick panel molding, then under the BCM/Junction block cover (while on my hands and knees

), then butt connecting them took a heck of a lot longer than when I did the H3. (And I believe those three wires disappeared in 2004.)
On the H3, pulling the A-pillar is less than a minute, if you have the screwdriver in your hand, and if you have side air curtains, there is no problem since the inflater module is at the rear of the door, and only the tie strap is in the A-pillar.
DRAGON:In regard to finding the accessory fuse; evidently, you have not looked for the accessory fuse?

It is under the hood, on the left side of the engine compartment. There is no I/P junction (fuse) block on the H3; all fuses are in the engine compartment. That requires running the wire out through the body harness grommet, (after you run them down the outside of the I/P), and the grommet is stuffed quite a way up under the I/P. I do believe taking a minute or two to remove the A-pillar molding, and butt connecting two wires, is a lot faster. Or, use that cord shown by Corvette OJ.
