Three Amigos — Time to deal...
I've been ignoring the Amigos for too long now. Time to deal with them.
I had to get $1000 of brake work done just to get the brakes up to scratch - rotors, pads, stuck callipers... that kind of thing. Turns out I just don't drive her enough for outdoor storage. I'll try to learn from that...
My cheap ELM wifi reader can't see any codes.
But I had a shop pull these codes (and I quote):
Wondering about "Option B" from here:

Looking for advice from the group. Thanks in advance.

- 135 Engine Speed Input signal dubious
- 134 Shuttle Valve Switch electrical failure
- 76 ECU Ground or Reference ground fault
- 73 ECU Internal valve relay fault.

Option B should certainly be done. It’s cheap, very easy to do, and fixes the known bug inside the Wabco Unit. Then you should get yourself a scantool that can read LR ABS faults (makes your life a breeze trust me), and after Option B it should just be an ABS sensor issue which also isn’t hard.

Alright, I suppose that's the best corse of action. Sure with it wasn't wintering out so much...
I do have one other suspicion — one of my wheel hubs came with a severed cable that I very carefully fixed (was not worth shipping back to the UK). But snow, salt and ice... I suspect I should open it up and see what state it's in.
Thanks guys!

Option B fixed mine and no more issues and I had the ground issue too and it was a pain to find and fix.
What I found was loose grounds in the left and right kick panel area to be loose and drivers side was missing the 10mm nut and not connected at all.
once that addressed all has been great

Good point on the wheel sensor.
Is there a list somewhere (in the rave?) of all the ground points?
and is there a logical way to check a ground with a multimeter, or is it it just, inspect, clean and tighten?

Most likely the wiring inside the Shuttle Valve Switch assembly is all cracked and causing ground faults. I personally install a new Shuttle Valve switch assembly whenever I do Option B so I won't have to mess with it for a very very very long time. However if the Shuttle Valve Switches test good (they usually do) then just cut off as much of the bad cracked wiring as possible and using a 3M Butt Splice connector then add the 2 wire trailer type plug harness and run it out the bottom of the Switch assembly.

Hmmm... just tried to take a look at grounds. Other that the ones around the main fuse box, I haven't the first clue where to look. Thought it would be the kind of thing I could work out, but... Had a look around under the passenger and drive compartments. Sure are a lot of wires... 
Might be because it's winter and my patience is limited.
If anyone has shots or hints of where the grounds are, that would be helpful.
