So I'm trying to hook up four Hella 4000 Rallye compacts to my roof rack and it seems that there is too much stuff, airbag electronics I'm guessing, to easily run the wire down the A-Pillar like you can on a D2. I have the two (short) Hella wiring harnesses that came with the lights which probably won't extend to the rear of the car, but if that's where it needs to go then I'll get some more wire 
So the question is, "What is the best route to run the harness from the LR3's roof to the battery?"
Thanks in advance
