Here's the one I used.

It has a ring terminal (so you can use any gauge wire to reach it from your battery) and 4 available 4 gauge outputs. I have 1 for the starter, 1 for both those plugs twisted together (alternator and fuse box I believe), one going to my electric fan relays and the last is open. I may eventually run it to a remote positive terminal so I can charge or jump from the engine bay but for now it's just empty.
Prior to installing it, I just had them all terminated in ring terminals and connected via bolt wrapped in electrical tape. This is much cleaner/safer. I do still need to come up with a bracket or mount to secure it.
