No power at all, help with wiring please

The more I look around the more I think the previous owner didn't know what he as doing and messed up the wiring. The red wire I circled in blue goes to the firewall but not thru the bulkhead. Just up thru a small hole

That may very well be a "MAD bypass already done" which is highly recommended on these cars.
Follow it and find out where your power loss is.
