Step 4: Tapping into the lines
I repurposed an old internal CD audio cable to plug into the three pin audio connector. The cable had a four pin connector and with a little bit of work I was able to reconfigure the connector into the three pins I needed. It was a tight fit, but I decided to tap into the lines inside the Media Dashboard. It has an open frame which made it possible but it took a lot of patience to slip the taps around the correct wires, insert the wires from the audio cable with the modified connector, and squeeze the taps together.
I cut apart an old Molex Y power splitter cable to get a male Molex 4 pin connector to get the 12 volts to power the VU board. My computer’s got plenty of extra power connectors so I’m not concerned about running out of power connectors in the future.
