Is that that IPDM thing from a few years ago that a lot were having problems with if not might be for memory ie computer presets an such maybe something that needs constant power but I don't know it's a good question and I don't think I've never come across anybody asking or explaining what that actually goes to. I wouldn't but I guess you can chop em off if it still works then it's a go lol sorry I can't sleep but I'm in I'll keep looking at this thread just to see if you find out what they're actually for goodluck
