Battery wiring upgrade

The easiest way is to Buy marine grade cables and crimp your own ends on. It took me about 2 hours to do all the cables including the junction box. It did cost about $50.00 for the cables in marine grade.

You do not need "Marine grade" cable. This is a truck, not a yacht.

Welding cable works great. Couple that with some adhesive-lined heatshrink and you're golden.

I make them out of the above, with the ends soldered on, and have NEVER had a problem in 20+ years for any on my vehicles or anyone else's.

Problem solved, problem staying solved.
