Wiring, Connectors and Hookup Information
For Classic Car Units
How to Determine Which Wires Connect to What

EQUIPMENT REQUIRED:  12 volt power supply, volt-ohmmeter, DC ammeter and 2 test speakers

1.  Connect negative ohmmeter lead AND power supply negative lead to unit chassis (ground).
Also connect the (-) lead of both test speakers to the unit chassis.
.
2.  Set ohmmeter to R x 100K range or higher.

3.  Turn radio on and off repeatedly (or insert and remove a tape if an 8 track-only unit) while touching
the positive ohmmeter lead to each terminal (or wire).  When the resistance suddenly goes very low,
you have found the wire for +12 volts to the unit.

NOTE:  If unit is a Delco 8 track player only, there are TWO wires that will drop the resistance.  The
correct  wire is the one that causes the unit to draw LESS THAN 5 AMPS when powered up.

4.  If a Delco 8 track player, note which two wires drop the resistance.   Connect the positive power
supply lead to these wires one at a time, turn on power supply and insert a tape.  Identify the wire
causing unit to draw LESS THAN 3 AMPS as the +12 volt power wire to the unit.     

5.  With the unit powered up and running, touch the (+) left speaker wire to each unit terminal until
you hear music.  Rotate the balance control to determine which (+) speaker wire you have identified,
then label that wire accordingly.  If front and rear equipped, repeat step to identify these wires also.

6.  Repeat step 5 for the right speaker (+) wire.

7.  Remove the tape, then use a voltmeter to determine which wire sends power to the radio when
tape is removed.  Identify this wire as "Power to radio".

8.  Reduce power supply voltage to 3 to 6 volts.  Remove power supply positive wire from the unit's
wire or connector, then touch it to the remaining wires or terminals.  When you hear a click from
the left speaker, you have found the left "To Radio Left Output" wire.

9.  Repeat step 8 for the right side.

10.  If unit is equipped with a power antenna wire, it will have +12 volts on it with radio turned ON only.



This Completes Wiring Identification on "Any Type" of Unit
Any Type of  COMMON SPEAKER GROUND  Radio, 8 Track or Radio-8 Track Unit:
Aftermarket Units - Kraco, Sparkomatic, Clarion and No-Name Brands

Smaller units with the familar 4 pin connector (or wires) generally follow the semi-universal color code:

Red ------  +12 volts          Black ----- Common         Green - Left Speaker       Grey - Right Speaker

Note:  To make your own connector, solder wires to short pieces of  #12 Romex construction wire - insert Romex pieces into connector.

Important Note on all Delco Standalone 8 Track Players

Chevy, Buick and Pontiac units use an identical 8 pin connector.  However, they are not wired the same
internally.  Plugging a Chevy unit into a Buick will likely blow a fuse and could damage the unit.  The
buyer should make sure that the unit purchased is the correct unit for the car it will be installed into.
Note that even some '70 Pontiac units WON'T work in a '69 GTO and will damage the amplifier.

PLEASE NOTE:  As the speaker and power switching between a Delco 8 track and radio actually takes
place inside the 8 track unit, the radio will not operate until the 8 track unit is reinstalled.
