Got my Grand Wagoneer working again ! As I wasn't up in Edinburgh as often as I wanted the last couple of years, I didn't tax it or MOT it ( MOT is the annual inspection test covering emissions and roadworthiness). Anyhow, having done some work on the rather dodgy original wiring, and the rather dodgy amendments to the original wiring, I'm driving it about again.
I'm missing the original cruise control parts (doubtless hard to get here), the air con doesn't work particularly (not really a problem here and presumably it contains R12 which is banned ??) and it likes to bleed a little on the road now and then, but it does drive nicely.
If you have a FSJ in the UK, get in contact ( jeep at milne dot info ).
