Dash harness replacement and upgrade.

Couple questions-

I'm gonna drill out the bulkhead connector and run 10ga for the red and black wires. What amp fuse should I replace the fusible link with?

The harness I got is slightly different. I had to add the ac harness into the bulkhead connector, and will have to run a wire for console lighting. The switch for the passenger door has two female connectors on my old harness, where the new one has only one. What do I need to do about that?

Can anyone identify what year the new harness is from my pic above?

Thanks.
