Cor-Har Schematics

I am trying to connect my ipod to operate through the factory radio without having to purchase the Cor-Har. Do you know of anywhere that has the schematics for the GM Cor-Har harness so I will be able to wire the GM B adapter to the plugs found in the passenger footwell. Any help would be appreciated. Thanks

you will still need an "interface" though.

Someone here has the schematics for the harness - all I remember is that one connector has the power and ground - and the other has the L/R audio (their grounds) and the serial data line as well.

yeah interesting thread. I don't have a stock deck anymore. But I would like to see the schematics for the interface.

the changer acts as the interface if you have one and just switching the audio signal... but without it.. .hmmm...

And this enables the AUX inputs on the radio

The one made specifically for the IPOD will decipher the serial commands from the head unit for STOP, SKIP, PAUSE... and control the basic functions of the IPOD.

Trust me on this one... just buy the interface and save yourself some stress.
