Default 69 c3 radio help

I’m hoping someone can help me with the correct wiring for my factory radio.

I have a line output converter with 10 ohm impedance (made by Pyramid) that allows me to hook the stock radio into an amplifier. You run the original speaker wire into the converter, and it outputs a pre-amp signal via RCA cables that can be plugged into the amplifier as an input. The best part is, because the converter has 10 ohm impedance, it should allow me to avoid the issues that normally come with hooking an old Delco radio into modern lower-impedance speakers.

can someone help me identify which wires to connect to the line output converter? I took a pic of the inside of the radio output wire block. I have the blue yellow and green wires that connect to the factory converter but the speaker wires have been altered. What were the original speaker wire colors and where should they be connected to the wire block.

see attached pics.

Wire block. Speaker wires missing?

Orange and white wires not factory?

Wire block diagram. What color wires should be in 1st and 3rd position? Are these speaker wires?

Line converter

Diagram for line converter.

Unfortunately, I can't help you but maybe JV Restorations can. They re-coned my '69 factory speakers to perfection and seemed very knowledgeable on the phone.
