Lights on the back of roof rack

[Havik]

I have a 30" LED light bar that I used to have upfront (which has now been replaced) that I want to place on the back of my roof rack. I am wondering what wiring harness to use? I can't find one with anything longer than a 12' lead and I don't think that is enough to reach the back of the roof. If it matters, I have the Gobi Stealth rack. Thanks for your help.

Extend the wires

Extend the wires

Is that what people are doing, or is there a harness I can buy that is already long enough? I would rather buy a harness that fits rather than extend the wires if I can help it.

what harness are you looking at? I am not aware of many using any premade harnesses. Are you talking about the harness that came with the light bar from say Rigid etc?

I buy the PIAA harness from eBay and add wiring to them. Did that for the front and both rears...
You can barely see the 2 harnesses for the rear in this pic right side just behind battery and fuse box:

I'm talking about something like this:
