Driving Light Smart Harness Installation Guide

Please remember that every vehicle is different in terms of engine bay so your steps may vary slightly. 

We have set up both an instructional video & an in-depth blog post regarding wiring your LED Lights to your vehicle.

INSTRUCTIONS

1. RELAY INFORMATION.
Locate a suitable mounting for the relay which is in close proximity to your battery to ensure the positive and negative cables will reach the + & - terminals of your battery. Do not connect to these terminals just yet. Check that the switch and other cables can reach the desired locations ensuring all cables are routed away from moisture and heat.

2. DISCONNECT POWER.
It’s always safest to disconnect running power by removing the negative (-) terminal from the battery for the easiest installation.

3. SWITCH LOCATION.
Run the switch through to the inside of the vehicle's cabin via a pre-existing rubber grommet in the firewall.

4. DRIVING LIGHT CONNECTION.
Find a suitable pathway from the relay to your driving lights that are clear of heat and moving objects and connect using the pre-fitted waterproof connector.

5. PIGGYBACK ADAPTOR.
Remove your high beam plug from the rear of the headlight and connect it to the piggyback adaptor supplied. The other end of the piggyback adaptor will then connect to the back of your high beam globe. The last end of the adaptor (White T-Connector) will connect to the STEDI Harness.

STANDARD PIGGYBACK ADAPTOR

VEHICLE SPECIFIC PIGGYBACK ADAPTOR

As displayed in the below diagram, the vehicle-specific piggyback adaptors do not plug into the vehicles' high beam globe but instead the main power plug for the headlight as a whole. As some vehicles are moving to HID or LED from the factory thus removing the traditional plugs found on a halogen globe and the standard connection (H4, HB3, etc...) the vehicle-specific adaptors will pick up a signal from the main power connection to the headlight to maintain a clean and easy install.

6. FINAL STEP.
Connect the red power cable to the positive (+) terminal of your battery and the black earth cable to the negative (-) terminal. Check that all connections are securely fastened and finish the installation by reconnecting the negative terminal to the battery.
