Hayman Reese Smartclick™ WiringEvery new release Hayman Reese towbar now comes with Smartclick™ intelligent wiring solutions. The key feature of Smartclick™ is that it is a modular wiring solution and will allow you to easily utilise any additional Hayman Reese wiring accessories as required, including the Hayman Reese body harness program.
Another key feature of Smartclick™ is that it incorporates dedicated connectors providing superior wiring connections. These dedicated connectors remove the need for scotch locks and soldering. Scotch locks are a “quick fix” providing unreliable connections which have an increased risk of deteriorating over time. Soldering joints may result in damage to your vehicle electronics if not executed correctly.
