With some work around the house done I have ventured out to the garage a few times.
The rear loom was ordered and I have sourced extra wire and connectors for a few additions to the loom. The loom is now plugged into the rear lights and the main ground has been fitted with some (nerd alert) amazing ground washers. I forget there name but they will cut into the paint to give a nice connection to the body work. Genius :)

Whilst I'm nerding out, I also got some grommet material, so re routing the loom should be a little easier to do, just cut the U channel to length and pop it in.

I think I have decided on the best route for the loom to run and I can still pick up one the under rear seat lights and under dash lights, I have also found the right placed to add the modern stereo loom plug, usb charger and glove box light. The last 2 will prob be left capped to hook up later when the final dash is installed.

So it hasn't been quick or vast progress but a really good step forward. It does look like the loom is going to fall short of connecting to the engine loom but that will be easy enough to extend and worth doing to get the loom tucked away and safe.

Was on the sand blaster and powder coating again, black this time and while that was out I had to re do the bonnet catch. That red was just not working for me, so I'm happy now.
