66 C10 New Wiring Routing

[Afirehawk1]

Trying to find how the wiring routes in the following areas.

1) Engine harness from starter to alternator.

2) Interior light. Appears to go from fuse box to the back side of the door jamb. i found some clips there. Does the wire travel down/thru the channel under the kick plates?

3) Rear lights, etc. No idea how it goes from fuse box under the dash to the rear?

Any good drawings or photos for reference.? thanks Keith
