I used this as a reference.....but when it is connected as in the tech tip, it does not work...need some help/guidence from on how to install a CD when the 3 wire connector is missing and this is in a 97...the tech tip is on a 98...should not be any difference but the color of the wires are different.

98 corvette

Three wire Signal CD/Radio connection
1)SW +12 out C1(8) DK GRN, Radio "ON" signal
2)Power C1(10) ORG (always hot ??)
3)ground C1(5) BLK/WHT

The last one is a lot more of a challenge 1) Radio signal = DRK/GRN There are several shades of green so again use the CD wire harness as a color guide in the search. This color seems to be used as a communication link for several components in the system so you will see this color wire used a lot in that "wad" of wires but only one or two of them are the ones you need. The way to find the wires in question is to pull the fuse panel and remove the box from the firewall (don't disconnect any wires). In the back of the box about midway are two of the dark green wires that are together put a probe on one of them and do a continuity search at the "wad" for it. When you find it strip a bit if the insulation away and connect the last 8 incher to it (DON'T SOLDER YET) now actually connect up all three wires and fire everything up with CD's in the 12 disk cartridge. If it is not working (the unit will take and shuffle the CD's but no music) then you tapped into the wrong Dark Green wire so keep tapping until you found the one that enables the system and then solder it up.
All should now work as intended so go ahead and finish up the install.
Now all there is to do is enjoy.


97 corvette Info from ENTERTAINMENT 8-113 RADIO - C1

It is a Kenwood changer, model KDC-C717, 10 disks

Now, my colors for the radio C1, were a little different as listed below and I showed the pins as well.

Three wire Signal CD/Radio connection

pin wire color circuit function
1 gry 118 speaker Return - LT FRT
2 tan 201 speaker Feed - LT FRT
3 dk grn 117 speaker Return - RT FRT
4 lt grn 200 speaker Feed - RT FRT
5 blk/wht 351 Ground Clean
6 pnk 314 Radio Signal - ON
7 - - not used
8 dk grn 145 Power Antenna Relay Feed - Coil
9 - - Not used
10 orn 440 Fuse Output - BATT- Type III Fuse

Now I have used the below listed and do not get anything but disk shuffling
1)SW +12 out C1(6) PINK, RADIO SIGNAL ON
2)Power C1(10) ORG (always hot ??) Fuse output - BATT - type lll fuse
3)ground C1(5) BLK/WHT Ground Clean

(If I go to C1(8) Dark Green , Power Antenna Relay Feed-coil I get nothing that I can disguingish and not even the disks shuffling).

can anyone with audio knowledge assist me in the wiring. thanks, Tom

I can not believe that no one was able to help you. Try to post this on the electronics board.

Bill, thanks for the looking...I did post it in the Audio at the same time I posted here....answers on the audio as of now is the same as here. will give it some time. I have the GM harness from the rear...its a Kenwood unit and it worked on the 99 FRC it come out of...but I only had one of the body harness plugs under the passenger area. Will sleep on it tonight. till later, Tom

 

Tom

I saw some where that there was some sort of modification that was needed to be accomplished under the dash when you have only the one plug.

Did you do any searches in past post on CD Changer install or 12 Disk CD changer ect?


Bill

 

Yes I did and came up empty....unless I am not doing something correct in the search parameters...but it has returned threads before for me. Eventually it will get figured out. Thanks...tom

 

Anybody able to provide assistance on this ....I also posted in the Audio section but no responses there either. Thanks in advance for any help. Tom
