•Purple Wire – Dimming
To dim the display 50% when the headlights are turned on, connect to the parking lights
DO NOT connect to the headlight rheostat control wire
For permanent 100% brightness, connect to ground
•Tan Wire – Par ing Bra e Indicator
Connect this wire to the negative (-) side of the parking brake light switch
If you are using a one-wire switch, you may need to replace with a two-wire switch
•Brown Wire – High Beam Indicator
Connect this wire into your high beam circuit This wire receives power when the high beams are on
•Gray/White Wire – Right Turn Signal
Connect this wire into right turn signal circuit
•Gray/Blac Wire – Left Turn Signal
Connect this wire into left turn signal circuit
•Yellow Wire – Fuel Gauge
Connect this wire to the existing fuel level sending unit’s signal output
•Blac /Yellow Wire – Fuel Gauge Ground

unit’s housing
•Green/Yellow Wire – Chec Engine Indicator
Connect this wire to the negative (-) side of the Check Engine Light circuit The Check Engine light

•Tachometer
To ensure that the ignition system does not interfere with any other dashboard functions, do not
run the tachometer wire alongside any other sender or input wires Do not use solid corespark
plug wires with this dashboard system Solid core ignition wires cause a large amount of
electromagnetic and radio frequency interference which can disrupt the system’s operation
There are a few ways the green wire could be connected:
◦If your vehicle has a separate ignition coil, connect the green wire to the negative (-) side of
the coil – the wire that goes to the points or electronic ignition module
◦If your vehicle has a GM HEI ignition, connect the green wire to the terminal marked ‘TACH’, or
on some systems, a single white wire with a spade terminal
◦If your vehicle has an after-market ignition – some systems will connect to the TACH output
terminal
◦If your vehicle has a computer-controlled ignition system, consult the service manual for the wire
color and location for tach signal output
◦If your vehicle has a magneto system, connect the tach signal wire to the negative side of the coil
Do not connect the tach terminal to the positive (+ or high voltage) side of the ignition coil Many
tachometers, shift lights or RPM-activated switches will not read directly from a magneto, so your
installation may need a magneto signal converter to function properly
