This would be a good time to test the installation of the Steering Wheel Button Box. After having connected the
power ground and signal wires, turn the key on. With an ohmmeter across each pair of colored output wires, you
should see an open circuit with no buttons pressed. With each button pressed, you should see a short circuit across
the colored wire pair associated with that button. See the previous page for your GM vehicle to see the button to
wire color mapping.
Pressing Multiple Buttons at Once
You can push multiple buttons from the same button group at the same time, but only one of the button functions
will be activated. The button in the group with the lowest resistance of the pressed buttons is the only button that
will work. See Page 8 for the resistances associated with each button. For example, if a Corvette VOL+ and VOL-
are pressed at the same time, only the wire color associated with the VOL+ button (Yellow) will be activated.
For vehicles with both cruise and audio signals, one button from the cruise control buttons and one button from the
audio buttons can be pressed at the same time. Note that the ON switch enables or disables all of the cruise control
buttons in that mode.
Connecting to Accessories
Connect any of the colored wire pairs to whatever accessory you want controlled by the corresponding steering
wheel momentary pushbutton switch or the cruise control ON switch. Each switch output is rated to 120V and 1A.
Higher rated signals must be controlled by an external automotive relay.
The GM Steering Wheel Button Box typically draws less than 20mA quiescent and less than 140mA when one or
two buttons are pressed.
Auxiliary Switch Units
All of the GM steering wheel buttons except the cruise control On switch function as momentary-on
pushbutton switches. The cruise control On switch is a mechanical toggle switch. If you need a switch
that functions as a toggle rather than ones that are only momentarily on (or more than one in a car with
cruise control), Accutach Co. has developed two different auxiliary switch units which can be used in
conjunction with any momentary switch (ideal for use with Accutach's Steering Wheel Button Box) to
operate devices which normally use a toggle switch (typical on/off function). These two different devices
cover just about any application. The Accutach Co. auxiliary switch units can switch circuits up to 120V,
1A. Switching higher voltage and/or current signals will require the use of an external relay. The
Accutach Co "On/Off Auxiliary Switch Unit" and the "Toggle Auxiliary Switch Unit" are described below.
On/Off Auxiliary Switch Unit
Some people will prefer to turn an accessory on with one momentary pushbutton switch and off with another
momentary pushbutton switch. The Accutach Co. On/Off Auxiliary Switch Unit provides two such circuits in one
small box. For example, the Corvette Steering Wheel Vol+ and Vol- buttons could be used to turn one accessory on
and off and the Up and Down buttons could be used to turn another accessory on and off. The Auxiliary ON/OFF
Box Install Guide will give you more information: https://img1.wsimg.com/blobby/go/1975f84f-4935-4131-8404-
5a914da1afb7/downloads/1c2pl1v81_301699.pdf.
Toggle Auxiliary Switch Unit
Some people will prefer to turn an accessory on with one momentary pushbutton switch and then off again with the
same momentary pushbutton switch. The Accutach Co. Toggle Auxiliary Switch Unit provides one such unit in a
small box. One of these boxes will be required for each pushbutton that is to be turned into a toggle switch.
For example, the Corvette steering wheel 1-6 Preset button could be used in conjunction with a Toggle Auxiliary
Switch Unit to power a brake line-lock unit during a tire-heating burnout. The driver would press the 1-6 Preset
button once to engage the line lock and once again to disengage it. The Auxiliary Toggle Box Install Guide will give
you more information: https://img1.wsimg.com/blobby/go/1975f84f-4935-4131-8404-5a914da1afb7/downloads/
