Dear Patrick

I apologize for the delayed response.

It appears that you are using two single pickups, with a humbucker in the bridge position wired to a 4-conductor shield wire, and the humbucker split connected to an on-off-on mini switch.
To assist you with the technical details, I've found a well-organized resource that may be helpful for pickup wiring.
Please refer to the following link:

Also, please ensure to check the color codes for your Rosewell pickups accurately.

If you have any further questions or need assistance, feel free to reach out.
Best regards,
