My 58 came with the electric wiper conversion kit mounted but not wired up. The PO did not leave the instructions anywhere and I am having issues getting it wired correctly. It has the 3 position switch and just had the ground and power wires hanging. To test, I ran the ground to the negative on my battery and plugged the power into the same blade on the fuse box as the blower motor. Nothing happened. If I run power directly to the battery the wiper motor runs but I wouldn't keep it like that as its pretty sparky when I touch the positive terminal, and it instantly blew a 25A fuse I had in between. The fuse in the cab fuse box didn't blow and the blower motor still runs

I am not having any luck finding the installation instructions at all and was hoping someone here could give more insight on the wiring for these kits. From what I can see, it looks most like the Newport kit. Just the switch, positive and ground wire, nothing else like any connected inline fuses.
