Not that I want to bring back a really old topic but where would I tap into an ACCY fused and switched 12V source for my Ramco mirrors and electric wiper kit?

Also, the previous owner replaced the OEM air bag compressor with a VIAIR 480C compressor using an SPDT relay with a 12 volt power source directly connected to the Coach battery NON-FUSED!! Shocked From observation and using X-7525B wiring schematic on the last page, the original wire for the air bag compressor is a 12 gauge brown wire that uses a glass fuse at the top of the fuse block behind the glove box. VIAIR shows Max. 12V Amp Draw of 23 Amps for the VIAIR 480C compressor and as I recall the glass fuse is 30 amp. I want to add a 30 AMP circuit breaker to the 12v source before there is an electrical fire but I want it switched through the ignition key ACCY circuit. Has anyone re-used the original wire from the OEM compressor when switching over to a VIAIR compressor?

Thank you for reading/responding to this post.
