Make your Xbox switch to AV mode automatically

Step 4 Adding the connector

Adding the connector

Now get the lid for the Xbox and in the lower left corner drill a hole just big enough to fit your RCA connector.
Solder the thin red cable to the center pin of the RCA connector and solder the black thin wire to the shield of the RCA connector.
Fit the connector in the hole and close the Xbox, it's done! 

Now you have an Xbox with a 12v (or 5v) output RCA connector lets modify our SCART adapter to use the new port.
