I need some help in how to run the wires from a stock harness in a 1976 Pig to a cs130. I suck at wiring so please bear with me. I just installed a National Luna dual battery kit (very nice) to power an Edgestar fridge plus all my accessories during a ~ 3,000 mi road trip I'm taking in August. My old 50 amp stock alternator can't keep up, and I think my external voltage regulator is on the fritz causing an 'excessive charge' warning on the Nat'l Luna system - so I'm going to install a 105 amp cs130 that is internally regulated. I've read everything I can find on MUD, plus a bunch off of MUD. It appears that the cs130 will mount to the stock 2F alt bracket pretty easily with a spacer on the long bolt (https://forum.ih8mud.com/3348915-post5.html) - the pulley can be reused from the 2F alt just fine. Since the cs130 is internally regulated I can unhook my external voltage regulator which is mounted just behind my driver's headlight (see pic below, circled in red), unhook the harness plug circled in purple and tape off, and tape off the currently unused plug circled in green, then toss the old voltage regulator in a box. Now run a 4 ga battery cable from the batt post on the cs130 to the positive terminal on my primary battery and no fuse is needed. No problems there but please correct me if I'm wrong. Now here is where I'm confused. Some places (CS-130 Alternator Wiring - Land Cruiser Tech from IH8MUD.com) say I need to use some of the wires from the stock alt plug, while others say to tape off the stock alt plug (see second pic below) for a rainy day and all you need is the one wire from the poss on the start to the positive battery terminal. I've read plenty of places where you have to get this right or you can fry your stock wiring harness. So which is it??? I would much prefer to only have the one single wire to the primary battery - easy, simple, done. Thanks for the help!
