Ernie,

Thanks so much for posting these. It will be a great help in sorting out where things go and how they get bundled together.

I noticed a combination of cloth tape and vinyl tape to wrap the harnesses. I hate the look of the shiny stuff, but it appears to be THE correct method. Can you comment on what is best and if any loom was used also?

Thanks
Oz

It sounds like I can use the cloth tape, non-shiny type then, and be correct for period. Thanks

I am collecting and preparing the electrical switches and such to begin the wiring. I have the panel switch, headlight switch, two-pole ignition switch, junction block (8-way) and need a military light switch to do the BO and service drive lights. I also have the bright indicator using partial take off and VPW parts. WIll post that later.

The headlight bright/dim switch was taken apart, innards cleaned and checked for continuity. It has some patina, but is original to the truck and works. I took the 8-way connecting block apart and used some threaded rod, cut to 1 3/4" length to rebuild it. The old threads were rusty and beyond use. Now I have bright new parts with great continuity.

Great work your doing there Ozzie. I did the exact same thing thing with my Juntion Block also. The gray on the Flathead looks real nice. Love the contrast with the OD. Carry on as they say. :D

Thank you. I am also pleased with the gray. Given mine is a 1944 replacement block, I think the gray is correct. Just hate that ugly silver :?

Am i correct in surmising that since this is a + gnd system, the + wire from the coil goes to the connection on the dizzy and the - goes to the ignition switch?

I corrected the wiring table for the WC12 by adding a note for where things passed through the firewall. There are two updates; 8-way indicates the wire is passed through the firewall via the 8-way junction block. FW indicates the wire passes through the firewall via the elongated hole shown below.I updated all previous versions posted here and in the wiring thread on the PW forum

I spoke with Steve at VPW regarding the ammeter and fuel sender hookup. He indicated the following as outlined in the diagram. He said the No1 position on the fuel gauge is supposed to be a yellow and black wire to the gauge and the No 2 a blue wire. I now need to confirm to which post on the sender the 1/2 coincide with.

Began to assemble individual wires one at a time, starting at the top of the list. I attached one terminal to an end and added shrink wrap. I connected that terminal to its respective post and then ran the uncut wire the length of its run to the other terminal paying attention to the wire loom hooks under the dash and on the firewall. That gave me an approximate length. I then cut and attached the loom and then soldered the terminal. I'll proceed down the list getting each wire complete before bundling them and wrapping.

I forgot to install the VR footer and had to take the firewall partially off to get bolts into the holes. I think the mounting should be the other way around, with the heads on the engine side. Will perhaps correct later. :shock:

I am using a 6v, positive ground, 25 amp solid state VR under the cover. No adjustment necessary, just replacee when no workee :lol: I have to remember to polarize the VR before putting power to it. Need to read up on that.

I'll post lessons learned at the beginning of the wiring posts above so no one starts down the wrong rabbit hole if doing the same.

I'll update the wire lengths when I get done.

Wire markers on the way. This will help later in life if things have to be redone or repaired.
