Marker lights on a Gatcombe

Evening campers! I acquired our Gatcombe about 4 weeks ago and, as you do, started a to do list. Had her re mapped @ Pendle Performance, purely for the extra economy . Last week spent several hours scrubbing the roof ( that was fun! ). This week it was time for a good waxoyling in Galgate. Throughout the month, I have been polishing and cleaning for dear life also. Now to next item on list. The r/h front marker light on the over cab has not worked from day one. So, I ordered new lens units from Alan @ Auto-Sleepers,(nice and shiny!), had a furkle and found that the live ( red ) wire was not connected as there wasn't enough length after a previous "repair". So, I took her to my local garage with a view to having the wire extended but he said there was no live feed to that side and that the wire was either burnt or disconnected/broken inside the body shell! I suppose the question in my long winded post is, can the wiring be accessed through the overcab cupboard? It looks extremely well trimmed in there.

Hi Lofty.
Did you ever get the market light issue sorted.
My marker lights need replacing.
Thanks Martyn.
