Since my Mk3 is now back on the road I've been back onto Gog and its getting quite close to driving out of the shed.

Several hiccups have delayed progress.

1. Fuel tank. The plans have been to lift the tank to the original height so the diff illumination can be seen from the rear.  When the tank was removed it was obvious that there was a fuel leak in the top folded seam, so the intended fix was the clean inside and apply a tank sealant prior to re-fitting.  Unfortunately when I started pressure washing inside the tank flakes of resin started coming away. On closer inspection the tank previously had a window cut in the side for a previous repair.  The result being the tank could not be reliably repaired/sealed.  Given that there were only about 5,000 109/110 forward controls ever made replacement fuel tanks are almost unobtainable and added to that Gog's tank had been further modified for the rear spare wheel carrier.  A new replacement tank was fabricated and that is now installed at the higher position.

2. Lamps and wiring. Head, side, indicator and stop/tail lamps have all been installed.  The front wiring fitted together with the original terminals to the standard scheme and worked first up (at least worked with the newly installed hazard lamp switch.  The rear has been somewhat more difficult. The indicator and side lamps were connected and worked by a system of trial and error.  Unfortunately the stop lamp wiring couldn't be identified at the rear even with a test pencil. The result is I've removed the spaghetti junction at the rear of the chassis which had original Land Rover, SADF and post service civilian elements and am now re-terminating all the wires in a logical system. It seems that the SADF installed a 7 function terminal block which would make things easier (if some of the screws weren't stripped). The problem is that the original green/purple wire has been cut at the end of the original Land Rover harness, so this hasn't been operational for some time. There is a secondary harness running through the chassis, which I'm assuming contains the SADF convoy lighting, but so far haven't been able to identify an active stop lamp wire.

Its all a bit awkward doing problem solving when you don't have either an SADF SIIB wiring schematic or even a civilian SIIB wiring schematic.

Currently attempting to identify wires at the front black wire white trace, black wire blue trace, brown wire green trace (runs to rear in secondar harness).  Any ideas?

Sounds like you're making progress - well done Diana.

I  am no help with the wiring unfortunately.

More progress late this afternoon, all over the metro area today (Arncliffe -> Warriwood -> Glenorie -> Leppington -> Arncliffe) so didn't get to the Chook Shed till almost 4.00pm.

finished off the modified long Defender mirror arms.

Then attacked the rear wiring.  A new terminal block fitted and  wires terminated (with artistic licence using the civvy trailer wiring colour codes and numbering).  Then investigated the absence of a stop lamp signal to find that the brown wire in the auxiliary harness.  This was only revealed when I discovered the front lamps had stopped working as a consequence of the convoy switch in the blackout position. Switched it back to normal, the front lamps came on and then was able to get a stop lamp signal at the rear. 

Normal front and rear lamps all now working.

Very happy.  8)

Also identified the black wires with white trace as the low brake fluid warning. This was achieved by studying the schematic in the 90/110/130 workshop manual.  Unfortunately the reservoir with the low fluid cap has been replaced with one from 101 without the low fluid mechanism.

took a couple of piccies on the phone, but was late in the day with low light  and poor shed lighting.

Mk3 Inter will probably hitch a ride on the back of the S-Line as I rather not spend all day and into the night just getting there. 

The decision then will be which to drive, Gog or the Perentie or the SIII Ffreddy

Gog will go to Ironfest and Camden Park 2017 and Corowa 2018.

The wiring seems to have been sorted.  Spaghetti junction has disappeared everything is neat as it should be and the NATO 12 pin socket has been wired in using the modified schematic (Attached).  I am wondering whether I should  install a double pole single throw change over switch on pins H and J to revert the wiring to standard should I tow someone else's trailer?

The convoy lights are working but the diff illumination would be a little difficult to see from too close.
