I did mine a little different. As I used the solenoid in the trunk so the long large line from the battery isn't live all the time, then from the alternator I went to this terminal block from Jegs.

Then I connected one post to the alternator, then all other accessories, plus the charge line back to the battery in the trunk (8 gauge, I think) on the other post. Then for safety I connected the 2 posts with a fused link wire in the event something overloads. All tucks up into the block and seems to work well.
