#2 and #4 fine strand welder wire is readily available at so many places like Tractor Supply, weldig supply stores, Lowes, Menards, electrical supply places, and the like. Some Home Depots carry it too, at least in our area they do. Crimp on, clamp on, solder on variety of terminal connecting ends in brass and copper also are at there places. Great for indoor as is or put a simple cheap split plastic cover sheath on it if used long term (years) in the sun and rain etc. I'm on 10 years so far with the rubber covered in a plastic split sheath welder wire going from my engine compartment with dual alternators down under and plastic tied to the frame back to the bed an up and it still looked including the wire cable rubber cover like new as the day I put it there. 11 years on the previous truck. We live in Michigan with ice, snow, rain, salted roads, etc. Wire is fused at both ends with 80 amp slow blow large marine fuses and a 80 amp slide switch to disable the #2 wire cable for high 12V current. None of which you get inside a TC!
