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.
Thanks Rod, that pointed me in the right direction. I found another video simply stating ground to the battery or firewall and wire the power to the hot side of the ignition. The fuse block in the cab should be able to provide that power should it not? I'll check it with the multimeter and see if its maybe not getting enough power.
The more I think of it, the more I like the relay idea. What do people do for grounding in the cab? Would it be worthwhile putting in a grounding block with a 10g wire or would i need larger? I already have a lot of wires everywhere just for my horn relay.
I found a new fuse block with built in ground points so I will give that a shot. If I want to go back I'll try and track down an original fuse box but the new one should make things a bit neater, I hope.
