This used to be a fairly simple thing to do, today it's not I'm afraid...
Because of all of the computerized systems, you Always have a draw and it can be difficult to determine what Is and Is NOT supposed to be there. The simple approach is to go with the Track Record of what causes a Parasitic Draw in out trucks first and try to eliminate them to see if you can just Get Lucky
Take the fuses out that control the Instrument Cluster and the Radio then disconnect the Alternators wires. Let it sit and see if, after reconnecting again, the batteries stood-up overnight. Maybe take a good look at the wiring for suspected Chafe Locations like over the Valve Covers and anywhere bundles of wires are laying on stuff. Roll them over and try to look at the areas they're touching. Does this happen predictably enough so you can know if it worked or is a hit/miss kind of thing (they're the Worst!)?
The more complicated approach is to try to track down the draw with a meter. This is NOT as easy as it sounds, there's a lot going on,,,,, But you need to disconnect Both Neg terminals and leave one Off completely. Then put the probes in the "AMP" holes (unless you've got a good meter and it can tell what you're doing) and connect one of to the bat post and the other to the cable end (doesn't matter which probes go where). This way, ALL the current going to your truck flows THRU the meter.
BUT as I said, there's a Lot going on so here's what you should expect to see. It actually takes over a 1/2hr for things to "settle down" as systems go off line. If you open the door, disconnect the meter or turn the key, it all starts over again. You'll see the draw drop slowly and should end-up at under 400mA (mine was at 180 finally but is a very Basic truck with few accessories).
Now what you can do is to pull some suspected fuses, but if you cause things to reset, like the GEM or PCM or interior lighting it all starts over. With this method you can determine a high current draw and where it comes from but it takes patience and time. Sometimes it's easier to just pull 50% of the fuses and see what effect that had, then the next night if nothing changed, the other 50%. Then 1/2 of that 50% and so on until you get close to finding where the trouble is located and go from there.
I doubt the recent "moving of wires" you did could be it, you had this problem before that too - right?
