Install Wiring Inside the Car (See Figures 1 and 2.)
a. Connect wiring adapter to the car’s existing wiring harness.
b. Connect an antenna extender cable (not supplied) to car antenna lead, if needed.
TYPICAL GM APPLICATION (See Figure 1.)
Radio Preparation:
NOTE: For GM car installations, use the GM Hardware Kit, Part Number 150-1331, which is
furnished with the radio.
1. Match quickie bolt locations on the ACD-75 radio to the factory radio bolt locations, and
snap the short quickie bolts (Item #2) into the appropriate locations.
2. Attach the original factory brackets or those from the radio mounting kit (if required) to the
ACD-75 radio using the supplied flange nuts (Item #4) or use the enclosed bracket
(Item # 6) if the original factory brackets are not removable.
3. Some vehicle applications incorporate a rear mounting support. Match the rear quickie
bolt on the ACD-75 radio to the rear factory radio bolt location and snap the long quickie
bolt (Item #3) into place. Thread the plastic rear bushing (Item #5) fully onto the quickie
bolt.
4. Plug supplied wire harness (Item #1) into the mating socket on the rear of the ACD-75.
Installation:
1. Connect the wiring harness from the radio to the vehicle side radio harness.
2. Plug the factory antenna cable into the antenna socket on the radio.
NOTE: GM vehicles 1992 and up will require an antenna adapter cable to convert the vehicle
mini connector to standard connector. Antenna adaptor cables are available at car
stereo speciality shops.
3. If a compatible CD changer is to be used with this radio, connect the DIN cable from the
changer to the mating socket on the radio. If an external amplifier will be used for the rear
speakers, connect the low-level output RCA leads from the radio to the low-level inputs on
the amplifier.
4. Reconnect the battery and perform a brief functional test of the radio to verify proper
performance.
5. After verification, turn off the ignition switch and fasten the radio to the sub-dash using the
mounting hardware previously removed from the factory radio.
6. Re-assemble the dash using the reverse of the disassembly procedure.
