Parasitic draw

Vehicle listed above is the Special Edition 4.0L Straight 6 4WD loaded. I have a parasitic draw and I need help to find it. I'd like help with the non intrusive method which is to check voltage drop across each fuse without having to worry about vehicle waking up... I was told a few things and I replaced the alternator, battery and computer but issue still remains. I have to disconnect the negative battery terminal every night so it won't drain the battery but this resets everything when I reconnect it.. Hard to pass NYS inspection when none of your monitors are ready... 200 miles later only the EVAP monitor wasn't ready and I passed... There is nothing on that I can see in the interior or exterior so basically I just need to know how to set up my multi-meter where and how to test fuses to narrow down which circuit and fuse or relay is causing the draw... Also, is there a way to check relays in the junction box under the hood without pulling them out and causing the computer to throw a code? What about the maxi fuses? The are a bit bigger with a clear cover on them can you test these as well? It's beginning to be a hassle to disconnect the cable every time, I thought about installing a kill switch but that doesn't really solve my problem so short of buying a smart battery charger or maintainer to keep the battery charged overnight I don't know what else to do.. Any help would be greatly appreciated... Thanks
