Help reading Jeep Wiring Schematics

I'm not sure where to post this but...

I understand probably 3/4 of what's on the diagrams but there's a few things I don't. Is there a good complete primer somewhere that tells me what things mean? I understand symbols, it's just some of the wire designations that have me stumped. Specifically, things like this, examples:

A wire with the following written within it:
E2 -?
20 -?
OR (orange, I'm assuming)

and

(8W-45-10) - appears next to a module.

Thanks!

Experience. It's what you get when you don't get what you want.

E2 is the circuit designation, 20 is the wire gauge, and OR is the colour (in this case orange, as you guessed). The 8W-45-10 reference is the wiring diagram (8W), system 45 (Body Control Module), sheet 10 -- it's telling you where more diagrams on the component in question can be found.
