Default Electrical Diagnosis Help

Pardon me for being not too bright here, but I'm wondering something:

Say you have a parasitic power drain. Say you've come up with a multitude of items that cause the drain, and the drain only goes away when ALL of the items are disconnected. Now say that ALL of the items are on two circuits with a common connecting point at the distribution block (parallel circuits, both main wires attached to the same spade connector which attaches to the distribution block). Now say that each of these circuits have other items on each one which DOES NOT show any signs of causing the power drain. How is this possible?? Is it that each item is causing it's own drain, or is it a shorted item (or relay or whatever) not de-energizing and causing a bleed-over effect?

My situation is as follows: I have the two grey wire connector at the distribution as the ONLY one causing my .068A power draw. On one circuit, the ABS Bat Fuse (fuse 4 in the under hood fuse block) pulls the draw. On the other circuit, the ECM Bat (fuse 4 on the instrument panel fuse block), The Courtesy Fuse (fuse 8), and the headlight switch (haven't troubleshot the fuses, but with the headlight switch disconnected draw disappears with all other drawing fuses disconnected) all cause the draw.

Just trying to figure this out. I know someone around here has got to be electrically savvy.

see if they share a common ground is about all i can think.

Looking at the Schematic, they're on G103, G104, and G101. Could it be a single shorted ground thats causing all those items to show the draw considering that they're on a parallel circuit??

Should I just chance it and cut one of the circuits off of the common connector to isolate each?
