Installation Guide for RELiON InSight Series Fuel Gauge & Remote Button

Quick Guide

This guide provides installation instructions for the RELiON InSight Series Fuel Gauge and Remote Button. These accessories are designed for use with InSight Series batteries. Important: InSight batteries should never be connected in series. Ensure all batteries are connected in parallel. The fuel gauge is constantly backlit and does not have an off switch.

What's Included

• 1x RELiON Fuel Gauge
• 1x Mounting Bracket
• 1x Fuel Gauge Cable Assembly (3m standard, 6m or 10m optional)

Fuel Gauge Installation

1. Power down the device and the first InSight battery in the string by tapping the power button once, then depressing it until both LEDs show solid red (approx. 6 seconds).
2. Attach the red ring terminal to the positive battery post and the black ring terminal to the negative battery post on the first battery.
3. Insert the CANBUS plug from the cable assembly into the provided CANBUS SPLITTER.
4. Route the other end of the cable through the mounting bracket to the dashboard. Insert the four-pin plug into the back of the gauge. Use zip ties to secure the harness and reduce strain.
5. Insert the gauge through the dashboard, seat it in the mounting bracket, and rotate the bracket to hold it firmly in place.

Remote Button Installation
