Bob, thanks. Brown/orange was what I meant. Starting to get a little confusing!

OK, now every wire has been labeled, tested a second time, some mouse chew spots have been fixed, and I added the necessary foot of wire to the fuel tank sending unit. (The spade of which broke off immediately upon attempted connection, grrr!)
The good news is that my previous estimate of PO wiring accuracy was low. This thing is 100% accurate, except now for the extension I had to put on the fuel sender wire (yellow was all I had that was a similar gauge). I also untangled the spare harness that came with the rover, and it, except for a few fried wires, is also surprisingly intact and complete. More untangling to do on that.
A few mysteries cropped up too, though. There was a purple/white wire in the dash, alone (not included in any harness bundle) with a lucas male bullet on one end, and a spade (female, I think) on the other. Anybody have any idea what that might be? I don't see purple/white on any of my diagrams.
Another is that I seem to have an extra wiper motor wire. There's Green (power from fuse box), Black (ground), The Red/Light Green and Brown/Light Green (high/low) from the schematic, but there's also a Blue/Light Green. (The Green Bible shows this as the Windshield Washer wire, so problem solved).
Also, I'm having trouble finding out how the warning (4-way) flasher gets hooked in. I have some ideas, but a couple of the wire colors are unique to that switch. I'm searching the board. I'm sure it's come up before.
And one final mystery, that fused Brown/Orange wire I mentioned in a previous post, actually terminates inside the cab. Since I have 2 wires (G/Y, G/W) hooked to the heater fan, I'm guessing the PO added that for the pass. footwell-mounted aux heater.
Now I just have to figure out the pinouts on the switches. The headlight switch hookup is specified in the schematic. The others I'll have to test, see what's what.Comment

Is that 4-pin section noted above a separate harness part? Does anyone know if there's a part # for just that 4 wire engine bay section?Comment

On GM vehicles purple with a white trace is the tach signal wire. the spade end goes to the coil and the bullet end to the tachometer.Comment

Good call, the PO did add some non-rover stuff as he felt appropriate (eg: Ford brake booster). So a tach wire might make sense (and it's removed).
The piece I'm still really stumped over is pictured. Wondering if this originally is a separate harness or part of a larger harness, if so what's it called and if anyone knows a part number or any other info about it? If I can't just replace that sub-harness part, I'll just get some parts and make my own, I guess.
Looks like the wires are:
Brown/Yellow - charge indicator wire from the alternator
White/Yellow - cold start/choke
Green/Blue - water temp
White/Red - Not Sure (should be ignition switch related, but maybe not)Comment

This is apparently the "engine harness" - makes sense. Josh at Brit wiring says $90. Our hosts online catalog says it's "$0.00," which is much more reasonable (Part# RNC527).
Even with this being my third Rover - and you'd think I'd be used to the irrationality by now ... $90 for a plug, four 4-foot lengths of wire, four bullets, and a wrap? Ouch.
Yeah, I know: kwitchyerbitchin'Comment
