Solder in RCA to factory radio
I'm finally fed up of burning CDs to play music in my 2004 Jeep Wrangler (TJ).
I know there are PIE boxes available to add an AUX input to the factory radio (I have the upgraded factory setup, with the 6.5" console sub), but I'd like to avoid buying one if possible.
Has anyone ever wired an AUX jack to a TJ headunit? Dodge/Chrysler used this headunit in a lot of vehicles.
Or does anyone have wiring diagrams/datasheets for the factory stuff? I'm an EE student so I should be able to figure it out.
