No power at all, help with wiring please

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.
So it's ok to bypass the bulkhead with this red wire? When I get home after work I will check it out.
2 seconds to jump across here with a screwdriver and that question is answered. :D
Then you saved a whole 3 minutes to do something else.
