Quik & Simple

Our Quik-Fit wiring harness is the ultimate play and plug system. If you have any forward facing auxiliary lighting, they must be installed to only activate with high beam and also have a manual override allowing them to be completely switched off.

The Quik-Fit harness allows for it all. With simple plug & play installation (H4 & HB3), it caters for positive and negatively switched vehicles. Thicker wiring and high quality sealed components will stand up to all the abuse you may throw at it. For the ultimate one stop shop for plug & play wiring system, the Quik-Fit is the solution.

Suits Modern Cars

As you may be aware, modern day vehicles are more complex and smarter than ever before. Gone are the days where a simple relay and wiring system will work. Multiplex and CANbus system’s are now almost standard on every modern vehicle which means you need auxiliary wiring to suit.

The Quik-Fit harness has been tested on even the most sensitive of CANbus vehicles, the PX Ford Ranger and latest Mazda BT50 with seamless results. With out modification, our harness works flawlessly without wiring modifications, soldering or splicing.

We will continue to invest in expanding our vehicle specific adaptor range.
