- Cable in trunk can’t be found
Most 1995 – 1999 Cadillac’s, Oldsmobile’s & Buick’s are pre-wired to the trunk. In
case you can’t find the connector in the trunk, please do the following:
1. Preparing the GM-A Cable
Take the GM-A cable and cut off the Black and Red harness, you will then have
two cables in your hands. One cable with the big white 22 pin connector and 1
with a small white 9 pin connector. You will use only the cable with the big White
22 pin connector (connects to the black box).
2. Connection to the 32 pin connector behind the Radio

*Some cars don't have the Brown /White cable to Pin # E10, the Dark Green/White cable to pin
#E11 and the Black /White cable to pin #E9.
In such case, please use from any other cable ( i.e. Ford cable) from the 22pin White
connector, the female pin. Just remove from the white 22 connector a Female pin and use it to
connect to GM radio missing pin. It fits perfectly. To remove pin from 22 pin connector, you can
shave of the plastic with a knife until you reach the pin.
