2012 JK Stock Battery Connections

Hey guys, first time posting here, been reading for years though. First a short anecdote:

I disconnected my battery before going out of the country for a few months because I didn't want to come back to a dead car. Well my inspection expired while I was gone and the OBDII diagnostics have all been cleared. I reconnected it, and have been driving around trying to get it to cycle, but after 100 miles I'm still "not ready".

I discovered my battery cable was loose because I stupidly connected my winch to the bolt that tightens the stirrup. I've since removed it and tightened it all up without losing power to the computer. I'd like to reattach the winch + cable to one of the three connection ports, but I don't want to disconnect the computer in the process.

The question at hand-
Despite all my best googling and forum searching I cannot find any information about what the 4 leads coming off my battery are for (individually). Does anybody here have the secret answer? (Not a picture of my actual jeep, rather one found on google but looks identical

So I've got (1) light blue, (2) dual red, and (3) a black cable(s) coming off the battery. I'd love (just for the sake of knowing) if anyone knew what all these are. But most importantly I'd love to know which one is the computer so I can leave it alone when I hook up the winch again.

ALSO- If anyone has an opinion on which port I should put the winch on, I'm more than open to hearing that also.

Thanks guys!

One red wire goes to the TIPM.
One red wire goes to the starter.
The light blue wire comes from the alternator. It has a fuse-able link in it.

I don't have any info on the black wire connected to the + terminal.

I don't have anything connected to that third connection point on my 2012. Don't know what that is either.
