Quick-Fit: Double Plug - Wiring Installation Guide

1. Remove Battery Connection
Disconnect both terminals from the battery. This is especially important for vehicles that operate primarily with CANBUS or other multiplex wiring systems, they can be very sensitive to new wiring connections.

2. Harness Fitment
Lay your wiring harness out and rough it in to ensure that all the parts of the harness are long enough for your specific vehicle. Gain an idea of how you wish to mount your relay, ensuring it's not obstructing any other serviceable parts of the engine bay - like fuse boxes, filters or sensors. 

Once you're happy with the route the wiring harness will take, now its time fully fit and secure it. We usually suggest cable ties.

3. Headlight Connection

Our Quick-Fit harness allows a direct connection to your headlight wiring to allow the relay to trigger off the factory high beam function of your vehicle. Supplied is an H4 and HB3 connection, fitting most Japanese vehicles with a conventional halogen headlight assembly.

Simply remove the factory OE plug off the headlight bulb/assembly and plug into the supplied adaptor, fitting the other end of the supplied adaptor back into the headlight bulb/assembly.


4. In-vehicle Switch

Supplied is a waterproof on/off switch which is to be mounted in the cab of the vehicle. This must be fitted to ensure your lights can be switched off when the high beam is activated.


5. Connect Your Lights To The Harness

Finally, you're ready to connect your lights to the harness. Also supplied is a wiring reducer (DT-P to DT), this is an adaptor that may be needed depending on your current or future setup.

6. Reconnect The Battery

Ensure all wiring is neat, safe and not going to dislodge over time. It's now time to reconnect the battery starting with the positive terminal (+). Check the fuse in the wiring harness is seated and lodged correctly and test the complete circuit by ensuring your in-vehicle switch is on and your lights activate when the high beam is activated.
