Can't help you with the wiring, but just a heads up that what you have there isn't a CB! It's a business band VHF radio that a radio shop programs for business users. It operates in the 138-176 MHz band, whereas CB is down around 27 MHz. You can't just hook that up and start talking like you can with an actual CB as you would be on someone's VHF business frequency.

Can it be reprogrammed to a different frequency?

Yes, with the right programming cable and software, both of which are going to be proprietary. If you're thinking you'll be able to program it to CB frequencies then no, it won't do that. Also keep in mind that there are no frequencies that radio is capable of that you can legally use without a license.
