Classic Questions regarding the future

Tackled the dashboard today. It is in, but not yet bolted down. Instrument carrier is in, but not fully connected, I need to figure out which way the big connector goes in, easy, all I have to do is match wire colors to indicators, e.g. indicator lights are up.

Figured out how to connect the parking break warning light, turns out the negative wire is already / still on the switch. Waiting for the trailer wiring to salvage the white cable to connect the fuel pump. Some of the other wires of that wiring loom will go to the gearbox, the slot for the warning light and the hole in the dash where the temp gauge will go, replacing the pressure gauge of the removed pressure tank. Then I can almost close the cockpit back up.

If it wasn't for two things: I need a bullet crimping tool to fix the butchered switch wires. And I cut the wiring of the rev gauge... Now I am looking at an unidentified, almost antique, VDO rev meter with for wires, red, brown, white-red and green. No idea which is which, I assume red is lights. Not sure so. I'll just attach some long wires, hide those behind the dash until I fugured out what is what.

Oh, and I removed, mostly, the dents in the roof from when the bonnet opened on the highway.

Solved a mistery, the rev counter. The red wire is 12 V plus, the grey-red one is lighting the green one goes to the coil plus and the brown one is the negative. All I had to do was to remove it from its housing... So rev green goes to the coil plus directly, rev red goes to maim harness white if memory serves well, rev brown goes to a convenient black negative or simply to a screw somwhere while grey-red goes to the main harnesses red, again if memory serves well.

The only mistery on the main harness is the heated rear window, not that the contacts are still there in my case. Originally the heated rear window had its own, original, harness connected to the main harness. All Land Rover factory, the wrapping of the rear window one was blue, but otherwise factory spec and it had Land Rover QA labels. The new harness seems to have those wires already included. To lazy to figure that out, so one part of the blue harness will be left in place connected to relay behind the glove box. The other one goes to the bin of original parts to be kept. The switch stays where it belongs for the looks.

Did check the rear diff without handbreak, it moves, at most, two degrees and not almost quarter a turn like the front one.
