Aux Rear Lighting! Help with jap wiring!

So I've got some rear lights on my roof rack and today armed with the tow bar guide someone popped on here in was hopeful.

As the roof wiring doesn't reach I've got some tow bar cable to bride the gap.

So following the grid ... This one


I started with the roof to tow bar wires to roof.
Tow. To. Roof. Function
Green - R Blue - Flasher
Yellow - L Blue - Flasher
Red - Red - Brake
White - Black - Earth
Brown - R Green - Side
Black - L Green - Side

So then I could follow the grid when at the cars wiring.
Started with the brake lights.
I connected
Red to the green/white & dots
White to the black


Tried this out.. Nothing! :dry:

But if I swapped them over


It works! But none of the others will :woohoo::woohoo::woohoo:

Anyone help plleaasse??

Just so you know jimnys are swithed earth not switched live and if your trying to pull more amps than the cable can carry it wont work what light are you trying to run on the roof

Ahh so can I not get around it? Nothing major just got these on my roof rack thought it be a nice touch

Would something like this work??
