Wiring Instructions - Intellitronix DP1102 Installation Manual

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 most use the provides sensors
and install new wires to new sensors
Note: If doing a LS engine swap, pick up the tach signal wire from the ECM/ECU and then set
the tach switch to 4-cylinders. You may also need to order the Intellitronix LS Engine Swap
Adapter Kit for Series 1, 2 and 3 engines. The part number is 8014LS. If you are getting the tach
signal from the ECU, the resistor in the adapter kit will help pull a stronger signal for the
tachometer. If your engine is a LS the Tachometer will need to be put into 4 cylinder mode by
removing Resistors if the Tachometer does not have a push button for programing, please call
Tech Support at Intellitronix, as you may need to send the gauge back to us to be reconfigured.
There is no charge for this additional service.
Ground – Black--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. Use 18 AWG or larger wire to
ensure sufficient grounding. Proper vehicle grounding is extremely important for any gauges (or
electronics) to operate correctly. The engine block should have heavy ground cables connected
to the battery, frame, and firewall. Failure to properly ground the engine block, senders, or
digital dash can cause incorrect or erratic operation.
Power – Pink--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 in the fuse box. Use 18 AWG wire to ensure the system
receives a sufficient power feed.
W ater – Blue - 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 best results we suggest running a new wire.
NOTE: THE FOLLOWING INSTRUCTION ONLY PERTAINS TO THE TWO TERMINAL SENDER AND
CIRCUIT BOARDS THAT ARE WIRED FOR THIS SENDER. NOT ALL KITS WILL CONTAIN A TWO
TERMINAL SENDER.
W ater –Black/ Blue - This is a ground wire for the two terminal water temp sender. 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.
Oil Pressure – Ground Wire- From the G terminal on sender will be wired to ground on the engine
block using 18 Ga wire to ensure proper ground
Dimmer – Purple 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 the Unit. This wire is looking for 12V to energize.
