Have no taillights, turn signals, brake lights, tag lights, and no power to F5. Believe all red wires are connected correctly. Also, my new dash harness has two RB wires and schematic shows only one connection (F5 to light switch)? Any help appreciated. thanks

No Power to F5

Yes. F5 gets its power from the light switch. The double sidelight switch and headlight switch wire together for the power, and the power feeds from the sidelight switch to the F5. Should be a brown wire.

I think you might have several issues looking at the list of problems so it might be helpful to break them down.
The complete lack of lights at the rear could easily be a lack of or a poor earth. There should be an earthed point that attaches to the body, right at the back of the LH boot floor - underneath the fuel tank. It would worth checking the bodies of the light clusters are all earthed properly - a black wire should run from a bullet connector on the rear of each light cluster to this earth point.
If the earth is ok:
The tail lights and licence plate lights would all be tied in with the lack of power at Fuse 5. It should just be a matter of checking for 12v at various stages: brown jumper lead between the two headlamp switches, (with side light switched on!) the Red/Black feed from switch, ditto at the fuse end (to rule out accidentally attaching the other R/B wire at the fuse) and finally the fuse is ok. The switches do get clogged up over time but they are fairly easy to dismantle and clean the contacts.
The brake light switch would require the brake system to be filled/bled. It is easy to test whether the rest of the circuit is working by removing the two wires from the hydraulic switch mounted on the bulkhead and connecting them together (assuming you have power to the green side of fuse 6).
I'd only look into the indicators once those are resolved.
