With the cooling system done, I got started on my electrical a couple of days ago. I'm going to be controlling the 46RH with a Compushift mini and pretty quickly figured out that that I needed to have the unit on hand so I could incorporate that wiring into the harness I’m building and figure out exactly where to mount the controller. I got that ordered yesterday and it should be here next week.

I also pulled the trigger on an Autometer electronic speedometer as long as I had the card out. When I initially set the dash up a few years ago I bought a mechanical speedometer……I could still run a cable and use that, but I was running into problems finding the recommend driven gear for the 4.56s (and knowing that the recommended one would probably still be a tooth or two off to actually get the speedometer to read correctly). The electronic speedometer I put in the ram 50 kind of spoiled as far as the ease of calibrating it by just pushing a button.

I’ve got the components outside the cab installed (lights, horn, senders, relays etc). With that done and waiting on the rest speedometer and controller to come in, I’ve been plugging away at some of the wiring. The work bench currently looks like a bomb went off, but I got a couple of minor changes made to the fuse box to make it compatible with the Chevy turn signal switch in the steering column and all the wires labeled. I also got some of the wiring on the turn signal plug done.



I decided a while back that I would mount the fuse box, ignition box and transmission controller inside the glove box to make it more convenient. There was no glove box liner in the 37 when I bought it but surprisingly they are being reproduced. The original style glove box liners are extremely deep however and they wouldn’t clear the heater I installed. My solution is to make a liner out of some old stainless I had left over from doing the floor.



Hopefully I’ll have the liner built this weekend and at least some more of the wiring done.
