Yeah I saw those haha, considering I already have the jack and the radio apart I'm going to go this route haha, what pics do you need?

I updated my previous post... haha. You may want to try to tap disc changer wiring if you have it.
Just pics of where you are thinking to tap in to. I have a 98 radio now too lol.

My concern with tapping it through the back is that it would not be amplified in a preamp and thus come in rather faint here are some pics, the board where the tape deck connects and the two spots it plugs in to The larger connector (this one looks to mimic the configuration of the cd changer connector in that LS1 link) The smaller connector And the tape deck itself

Inside the tape deck. This connections on the deck itself. That colored harness looks promising.

It would be no different than how the Bose sees the disc changer from factory. It goes through the head unit before the amp then to the speakers, I would think. Everything else is self explanatory except I am not sure if the Diagnostic Signal - Entertainment and Comfort needs powered 5v or 12v or grounded I've never really looked in to how the serial bus communication works... I will see if I can compare the plugs a bit later from your radio to LS1 thread.

Ahh, didn't read that post closely, the disc changer, that makes perfect sense. Hmm so pretty much it would trick the head unit to reading that theres a disk changer there ?
Does the non-bose work with a disc changer?
Btw, I'm non-bose and non-changer haha

Yah! That's what that device does... but if I could figure out how it works, it would be cheaper to tap it ourselves lol. Just don't understand the Diagnostic Signal - Entertainment and Comfort aspect just yet...

Edited my post at the end there lol
Btw, I will just wire into the cd player like the instuctions say if we can't figure out the correct wiring on the tape player. I'd just prefer to use the tape player instead of having to unplug the jack to use a cd

lol. Not harder really just done differently while keeping all OEM functions without dummy tapes, etc. Just throwing other ideas out there. The pre-made module would work perfectly. I am not saying this write-up doesn't work or isn't a valid option.
I might pull the radio and bench test some things in the future. Until then.... haha. You wouldn't need to have the changer wiring you could do it at the back of the headunit by adding wires in the empty cavities n correct location on OEM stereo connector plug.

It has been brought to my attention that some radios have a ribbon cable for the CD player.
We are working on a tape deck bypass solution for that reason

Yeah, guess who found out lol, looks like I'm stuck with the tape player, or CD changer solution. A good supplement to this thread would be This Tutorial by our good pal Randy. As you can see he has the ribbon cable as well. Dan tell's me he's had an array of radios from nearly all years (95, 98, 99), none of them having the ribbon cable, and they were non-bose like mine.......perplexing

Rob, the layout isn't identical, but very similar. I'd start with the assumption that the audio signals are still on the smaller connector, and similar pinout. So that blue wire (pin 1) should be a ground, then pins 2,3 and 4 would be the audio signals. You could test that with a voltmeter if you can power it up on the bench and play a tape. You should see little or no DC voltage and less than 1volt peak to peak AC voltage on the left and right channels. My concern with tapping it through the back is that it would not be amplified in a preamp and thus come in rather faint here are some pics, the board where the tape deck connects and the two spots it plugs in to The larger connector (this one looks to mimic the configuration of the cd changer connector in that LS1 link) The smaller connector

I was going to try some things but the factory headunit in this '98 is seriously fubarred. I may still be able to test some theories though(disc changer input). I have next week for vacation so I will have ample time to experiment. Will likely be using the main board for keeping SWC/Date.

Just thought I'd show my setup. Sorry for blurry pics, but you get the idea. The lighter sockets will be removed in the near future and USB charging port(s) installed. My brand new HTC DNA The only thing non-stock in h/u appearance is the Eject button is blacked out (and disabled.) Voice navigation works great while I'm playing mp3s (or iHeartRadio app), and if I get a call, the music stops and I can talk freely without changing to speaker phone and the caller plays over the car speakers. Pretty slick for minimal effort I think.

I tried adding pins/wires to a spare harness I had to emulate disc changer input. No success. They key is in the serial bus com., that for purchase module must emulate the signal the disc changer would send... need to use oscope to discover that and I don;t have a disc changer to catch the signal and thats too much work anyways for something I am not going to use haha.
FWIW, the wiring for disc changer is not in my '96 but wiring to add disc changer is in my '98. One of those modules would perfect for anyone who has the wiring or wants to add pins to OEM harness. No discs, no dummy tapes.

Fooling the E&C bus is the trick that convinced me to go with the cassette input. I do, however, think you could simply record the serial line like an audio file and play it back to fool the h/u. You'd need a small capacity MP3 player with at least one packet of serial data indicating that a disc is playing, plus a small amplifier to boost it back to serial bus voltage levels. I'll just keep my $2 dummy tape.

^^yup. Quick, easy, and effective is the name of the game. That's what I would do if I still ran the stock radio.

another thought Collins (after reading the Date/SW Controls thread again...) If your aftermarket h/u has rca outputs, you could route that into the stock h/u (with fake tape adapter setup), then feed the bose h/u line outputs to your amp. This would effectively give you a secondary volume control from the wheel, plus four channel balance/fader hidden in the console.

Right that is why the tape/cd mod is best for now unless you have the disc changer then the module is the way to go IMO for ease of installation. I just don't like the dummy tape/cd.
I would still be interested in seeing what the innards of that module are though just by nature haha. I have aftermarket to throw in the 98 anyways.
