2003- 2006 Infiniti G35 Manual Edition

Version: 1.1, January 2020

www.LCDdash.com

INSTALLATION TIPS

Before Starting:

Disconnect the vehicle’s negative battery cable before performing any electrical work on the vehicle,

or LCDi Gauge system. This system must be installed by a licensed automotive electrician.

Do NOT attempt to power up the system until the essential devices are connected, or the system will

crash. This includes all USB devices.

Do NOT remove any power, or ground wires from the modules while the system is active. Power down

the gauges and then wait two minutes before doing any electrical work.

Email: info@LCDdash.com for support.

Installation Considerations:

- Find a location to mount the Computer Module with a minimum of 1.0 inch clearance on each

side (excluding the bottom) to allow for air cooling.

- Ensure that the Interface Module, and LCD screen is with 3.0 Feet of the Computer Module.

- It is good practice to bundle wires from each section in protective loom.

- All power supply wires must be fused within 6 inches of the power source/battery.

- Any wires passing through a firewall, or conductive panel must use approved grommets.

Preparation Checklist:

- For systems with Electronic Engine Start, ensure that engine security is disabled, and any intelligent

key modules have been bypassed to allow the touch-screen Engine Start option to function.

- Clearly label all wires routed to desired areas of the vehicle where LCDi system modules will be placed.

- Window motors must have limit switches, or factory window stops to prevent damaging the DC motor,

and/or window regulator(s). Install additional limit switches if necessary.

- Any high-current loads driven by the system modules must have fused, relays with enough power rating

to handle the load.

Splice on OEM

signal wire and

extend to the

Interface Module.

R TURN

This model is setup for a 3 wire Boost gauge,

using a 5 Volt DC output signal. It can be

configured to work with OEM, or aftermarket

sensors

Default calibration is for 15 PSI, 0 to 5 Volt DC

voltage range.

If other ranges are required, the LCDiConfig.TXT

file must be updated.

with electrical tape to prevent shorting and fire.

Un-lock and close all vehicle doors.

Install the main battery, negative cable.

Open the driver door.

The system will begin to boot up. Within 6-8 seconds, the screen graphic image will appear.

Press the Engine Start/Stop without the brake pedal engaged to energize the Ignition. This

will prevent the screen from shutting off after 30 seconds of idle time.

OR

Press the Brake pedal and then press the Engine Start/Stop button to start the engine.
