CAR STEREO AUX INPUT TAPS into CD ribbon cable television
[Gezepi] wished to add an auxiliary input to the stereo in his 1994 Camry. At very first look there wasn’t an simple method to patch into the system. however a bit of probing with an oscilloscope as well as figured out that he might inject audio with the CD ribbon cable television shown above. The CD visitor is a self-contained system that receives commands with the cable, as well as passes analog stereo audio back to the receiver part of the head unit. We’re not sure exactly how he figured out which pins to tap into, however it may have been as simple as probing with some headphones while a CD is playing.
The degree of his hack is documented in the picture below. He cut the two audio leads on the CD side of the ribbon cable, then soldered his auxiliary jack on the receiver side of the cable television connector. This guarantees that two audio signals aren’t being piped into the receiver at the exact same time. sadly it likewise implies that he won’t be able to utilize the CD player. We have seen other techniques that utilize a special audio jack as a pass-through which cuts the connection when a jack is inserted. That’s the technique utilized in this Subaru hack.
