More pics of parts and progress, still not done. It's another one of those lazy weekend installs, taking my time
This is the battery, newly mounted:
This is going to be the positive cable run. I bought 15 feet, which is longer than necessary, will cut to size and use some of the leftover for the ground lug as well. This is 1/0 gauge copper cable, 19 strand, available by the foot at any hardware store (as are all the other parts I'm using so far, other than the battery and bracket themselves). I sheathed it in that corrugated plastic tube stuff, they sell it in 7 ft lengths at the hardware store as well (1/2" dia).
These Al connectors were nearby the cabling at the hardware store. The screw-terminal end fits my cable, and the other end has a nice little screw hole.
After removing the battery and unscrewing the positive battery post connector from the big inline fuse holder assembly, I screwed one of the above connectors in place of the positive post connector. Used an M6x1.0 screw, 16mm length, with lock washers on both sides (same hardware I used on the battery bracket in the trunk)
BTW, the factory negative battery cable just runs straight to the body, so it can be removed completely.
So now I'm basically down to doing the big cable run somehow, and then doing a tiny jump for the negative side from the battery to the trunk floor. Almost there...
