Thanks, J-Rod. I hope it helps some people that want to do this. One thing I'm big on is crimping and soldering. The propane torch definitely helps as it's difficult to solder 1/0 with regular methods. I made the soldered sections pretty.
What did you use to solder? Also keep in mind I'm OCD about everything with my truck. Write-up isn't here yet, big man. But it will be in an hour or so.
Say guys this might help one out my son-in-law was telling me that Napa sells lead pellets and the fittings so when doing the BIG THREE all you need to do is heat up the lead pellets with propane torch and you will have your thicker gauge wire ready to bolt on nice and tight.
