So as I understand your thoughts you suggest to run the multi strand 6mm cable from front to rear with no breaks then run a separate wire back up the trailer to each clearance light, is that right?
That is pretty normal but not possible on this trailer due to the way it was constructed
I still never cut the main trunk cable for the want of a better description, I open up the trunk, locate the cable needed
Strip a section of insulation off, wrap the cable around the tripped piece of cable, then solder that and heat shrink it
Do that to both cables + & - and then tape
Reinsert in the sheath and heat shrink all three together with a resin filled heat shrink
100% water tight when done
Hope that makes sense,
The trunk isnt cut along the length at all
Your better to die trying than live on your knees begging

The old legend that taught me the ways of the auto electrical trade explained it that if you solder onto your main cable you take away its main advantage of being very flexible due to its fine stranding and you may as well have used "house basher" wire as he called it and Ive seen plenty of failures caused by using said wire. I barely remember him using solder, he loved his tinned copper lugs and his clipsal 001 crimper and he bolted them together before he painted this black goo on them and sometimes taped them up, we never used heatshrink in those days, probably too expensive.
