Photos/photos/photos and ditto on all the above advice.
Been there twice now. Intimidating at 1st., but it will go back together.
Pull the motor and give er a good clean / paint. You might even get motivated to learn the fine art of aluminum polishing

Wiring will put itself back together as long as you took a few photos of the main junctions. One wire at a time., clean all wires and connectors while your at it.
On putting it all back together when you are ready. Little steps, little projects.
My theory on these rebuilds is to walk into the shop and put something back on each day. Even if its just turning a bolt or cleaning a turn signal lens. I assure you that if you do this...come spring you will walk in and there will be nothing left to do than fill the tank and turn the key. Some days you get in the groove and work through lunch and dinner, some days you are so pissed you don't want to look at it. BUT DO SOMETHING EVERY DAY.
P.S. If something has you stumped, leave it till later, do something you can do. I've found that by the time I get back to what had me confused, a week later it all makes more sense.
Have fun. Nothing like knowing how it all works
