I pushed the wire thru the firewall near the steering wheel. That's easy to do.
When I put the light in last fall I used the auxbeam switch and relay. The auxbeam light itself filled with water so I threw it away and bought the Rigid light. So the wiring is fine. It came with a 30A fuse.
The main light now is a 20" Rigid 120313 which draws 215 watts and I added the D series pro 202113 flood lights which draw 60 watts. I tied it all together under the front bumper. One switch turns everything on. The whole light output now is 274 watts which draws around 20 amps, so that 30 amp fuse is fine and the original auxbeam wiring works fine.
I tied the wiring on the light bar with black nylon ties and fed the wiring in a wiring loom and directed it down the left side light bar and I fished it near the left side tow hook.
Originally I went into the lower grill, but I put a plug in the grill and for this wiring went towards the tow hook. The upper grill is sealed because of the automatic louver inside grill and wanted to just stay clear of it.
Only annoying part of the whole set up was that lower air dam. It's just enough in the way where it blocks your view of parts placement and I needed to use an extension with a universal to tighten all the bolts up.
It worked, just it takes a little longer than I wanted.
The light bar mount is of excellent quality. If anyone wishes to do the same I recommend the mod.
On this video I showed how I ran that wire thru the firewall,
