Here's a couple picture of the "power distribution" panel I came up with. The panel mounts under the dash, against the firewall, drivers side, all the way up and to the left. You can see the new clutch activation rod in the last pic.

Top left is a ground terminal block, top right is the horn relay, middle section is a pair of relays I salvaged from the donor truck, they were the trailer tow package relays. One relay is for switched +12v and connects to the large red terminal block at the bottom. The other relay is switched by the headlight switch and connects to the small red terminal lug on the lower right (missing in the picture). I'll attach auxiliary lights to that lug (cab roof lights, trailer lights, gauge lights, etc). The single stud red block on the lower left is the battery lug (live +12v always). This setup will make adding and removing stuff easy now and in the future.
