They have a aluminum wire soldered in across a the modules every two inches. Positive on to top ground on bottom. I just picked the length I needed and cut it. I could have done a cleaner job if I took it all apart and used the band saw.Heh. That the kind of silly nonsense I'd do. Is each 4-LED module wired independently?
I have been looking at the space between the rear bumper and the fuel tank. Looks like a 18" x 7" diameter tank would fit.There's a good bit of room to the left rear outboard of the frame but the rear AC lines intrude a bit. Something like a medium-sized scuba tank would fit there, with some sturdy mounting brackets. Maybe no more than 5-7gal tank at 'normal' air pressures. Was just poking about under there the last couple weeks, with pulling the full tank and changing the rear coils and lubing all the rear suspension bushings. I'm thinking to put a tank there myself, a compressor where my rear sub is (rearward of your ARB install) and hard-plumbing QD couplers at both front and rear bumpers. I'd like to put a tank in too. And that rear quarter spot looks like a likely candidate.
