Installation; Set Up Window - Intellitronix N3211 Installation Manual

INSTALLATION:

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 - Red--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.
Tach Input – Grey - Connect to the negative terminal of the ignition coil, or if using a high energy
CD ignition, connect to the TACH output of your ignition system instead of the coil.
Tach Output – Blue - Connect to the negative/ground side of the device that you want to activate
at the desired RPM.
Warning: Most Late Model vehicles that do not have a distributor or have multiple coils will
require the use of a Tach Adapter.
If the device to which the blue wire is attached draws more than 3 amps, a relay must be
used to drive that device or damage will occur to the unit.
If your vehicle has a separate ignition coil, connect the gray 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 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.
