Anyone out there have a copy of the subject wiring diagram?
I've just replaced my 89 780 TD6146 with a CR-814 out of 91 Coupe.
Basically the Cr-814 is the same as the previous TD-6146 (Bertone 87-90), but has several additional features such as a mute button,anti theft and a CD controller ( most of the button layout is the same, but many of them have different functions and are labelled as such) My understanding is that the CR-814 was only available for one year and only in the 91 Coupe.
Most of the wires are the same out of the pigtail in the rear for the same functions and go into a standard 9 pin connector. On the previous TD-6146, only 5 of the pins are present in this connector and are all the same colour and positions as the CR-814. The CR-814 has wires going to all 9 connectors. When hooked up to the 1989 780 wiring harness and after entering the code, the radio functions perfectly, so I assume the only difference would be for CD control, which I assume is the purpose of the addtional 4 wires. The 814 also has 3 DIN connections on the back, one for the CD, one for the equalizer and one for the amplifiers(this DIN eventually goes to a splitter for the front and rear applifiers)(6146 only has the amp and equalizer DINs)
I have already run the DIN wire(91 coupe donor) and two additional wires (in anticipation) from behind the dash to the trunk when I swapped out my interior.
If anyone has an actual 91 780 wiring book, showing the radio wiring diagram, I would be most greatful for a scanned copy of this page. I have the OEM wiring books for the 89 and 90 780s but obviously, the 814 is not covered. These books are the only source for the diagram as they were unique to the 780 unless anyone knows what the equivalent radio was in the very late 740/760 range with a CD changer capability. (780 radios are the same as the 740/760 equivalent with a unique faceplate. Removing and interchanging the faceplate works well if your 780 raido display dies as I did it with my last TD-6146/TD 6141(standard 740 radio))
Thanks for any help.
