WIRING INSTRUCTIONS

Note: Automotive circuit connectors are the preferred method of connecting wires. However,
you may solder if you prefer.
Note: LS Engines or any other Computer based engine systems must use provided sensors along
with the factory sensors to send the signal to the computer
Use 18 AWG or larger wire to ensure sufficient grounding and power feed
Black – Ground This is the main ground for the display system. A wire should be run from
this board to the vehicle engine block for the best ground. Proper vehicle grounding is
extremely important for any gauges (or electronics) to operate correctly. The engine block should
have heavy ground cables to the battery, frame, and firewall. Failure to properly ground the
engine block, senders, or digital dash can cause incorrect or erratic operation.
Pink – Accessory 12V Connect the power terminal to accessory +12V power from the fuse panel
or vehicle wiring harness. Using a 5-amp fuse or an inline 5-amp fuse holder. This terminal should
have power when the key is on or in accessory position. Use 18 AWG wire to ensure the system
receives a sufficient power feed.
Blue – Water Temperature This gauge is incompatible with other sending units, so you must
replace the existing water temperature sending unit with the included sender. Do not use Teflon
tape or other sealer on the new sending unit's threads to avoid inaccurate readings. Connect the
blue wire to the sending unit. For the best results we suggest running a new wire.
Black/Blue – Water Temperature Ground This is a ground wire for the two terminal water temp
senders. If your dash kit came with the single terminal sender this wire will go to the engine
block ground. If using the two terminal sender this will go to the black/blue wire on the sender's
harness. If your kit contains a two-wire sender and your dash circuit board does not have the
Black/Blue wire installed, then run this wire coming off the senders harness to the same ground
that the dash board is grounded too
Oil Pressure – Orange Replace the existing oil pressure sending unit with the unit included with
your gauge. The Orange wire will be wired to the S terminal on the sending unit. This gauge is
incompatible with other sending units.
Orange/Black – Oil Pressure Ground Connect to the G terminal on sender
Purple - Dimmer Connect to the parking lights to dim the LEDs 50% when the headlights are on. However,
*DO NOT * connect to the headlight rheostat control wire, or the dimming feature will not work properly
and may cause damage to Unit.
Tan - Brake Connect to the parking brake wire from the dash to negative side of parking brake
light switch. NOTE: If you are using a one wire switch you may need to switch to a two-wire switch.
This wire is an optional wire some vehicles may not require
Brown – High Beam Connect the brown wire on the Dash unit to your high beam headlight circuit.
This wire is powered on when the high beam is turned on.
Green/Yellow – Check Engine Connect to the Negative side of the Check Engine Light circuit.
The Check Engine light will come on when using with a PCM or ECM.
Grey with White strip – Right Turn Signal 18-gauge wire is the - RIGHT turn signal
Grey with Black strip – Left Turn Signal 18-gauge wire is the – Left turn signal.
Voltage Gauge This Gauge Requires no wire hookup. Volt Gauge is built into the dash panel and
is powered by the main power and ground connection of the dash. It does have an Adjuster to fine
tune the voltage. Note: you will need to adjust it before fully installing the dash
Trip/Cal Button - Push button on Dash Used to easily reset your trip odometer or other
speedometer functions.
