I just had some wires run, there's a spot under the dash right above the pedals on the driver-side. There's a boot that I was able to get wires to go through. Not sure how difficult it was as I had someone do it for me. He used an add-a-fuse to tap one of the switched power fuses. Not sure which one though and then tapped on to the battery for the power. I had 7 wires run through so it can be done.
Wasn't too bad for the guy to do.
