    Delco Head Unit Inputs.

    Today I finally got around to hacking my head unit to have audio inputs. I've had the parts for about 12+ months (I'm not lazy, just busy) Once you have the parts and figure out how to take apart your dash. Then the job is a simple as just pluging a cable into the aux port of the head unit after a little bit of soldering. Info is up on my site. Look under "System" then go to "Audio".

    You will have to aquire a remote tape/cd deck. You can buy them new or at a junk yard. Pin-outs are on the site, for anybody who would like to hack it future. Aka fake the remote connection signal.

    The sound quailty is great. No hissing, buzzing, or alt whine.

    Any idea which of the slave tape units have the right pinouts? I know where I can get a tape unit out of an 88 chevy pickup but I am not sure it will work on the Delco unit in my 2002 GMC pickup etc.

    To my knowledge the aux connecter (9 pins) has been used since the mid 90s.

    Somebody with a little more knowledge in electronics could capture the "connected" signal and fake it. But that is over my head.

    The most I can tell you is this. You can disconnect the remote unit after accessing it the first time. As long as the radio stays on, it thinks the remote unit is there. Even after switching back and forth from AM/FM/CD. I've read that the E&C is a serial line, but what method it uses I don't know.

    I'm very interested in this as well but I cannot seem to locate it on your webpage. Your system page does not fully load.

    I hacked the delco unit in my 99 cavalier the same way.

    I ran a custom 9 pin wire to the trunk were I installed the cassette deck. I also installed a switch which switches between cassette and my carputer which is installed near the stereo.

    Works great, no sound distortion.

    I have a 2000 Yukon, and a similar rigged setup. Leave it to GM to overcomplicate a tape deck by adding a serial bus to it.. It probably uses the same J1850 VPW protocol the rest of the car uses. To interface it (or your car) with your PC, the only thing around is an interface from www.vehicleinterface.com - too bad theres no software.

    If you have an older, pre-digital, analog car you are probably in luck.. this type of setup might work:

    ...as you can see, GM used the same 9-pin connector back in the 80's as they do now, but the pinouts are all different so be careful.

    Could i some how get an AUX input out of my Delco Pontiac Monsoon cd-player head unit?

    Hey ODYSSEY, how do you like that steering wheel remote? how invasive is it? is it possible to mount it in a more cosmettically appealing fashion, that you can see?

    Yeah.. it's on the audio page, not the system page. Thanks though!
