The electrical system of a truck is responsible for nearly 80% of front & back upfitter issues—

and poor wiring and complex design can be difficult to repair. Our patented Keehn Klean Harness System was invented to eliminate driver frustration and repair time caused by badly designed or overly complicated wiring systems.

It's just one more way Keehn's experience makes your job easier.

CSP (Cab Switch Pack)

The CSP (Cab Switch Pack) configured with a printer and laptop running off the harness system through a dedicated plug.

ASP (Auxiliary Switch Pack)

The ASP (Auxiliary Switch Pack) allows you to control switched outputs at the rear of the truck, with brakelock and PTO indicator, so you can monitor system status BEFORE you go back into the cab.

Here's how the Klean Harness System can simplify your fleet, make future repairs easier, and save you money down the road.

Superior Design.

Circuit protection and switching functions are controlled by a powerful Cooper Bussmann VEC. Every single fuse and electrical item is present withinthe unit, meaning you won't have to struggle through locating and replacing circuits and connections for each component—everything is clearly labeled on the VEC. The Keehn VEC is designed to accommodate the most advanced systems and components so future upgrades are a snap.

Ease of Operation.

The connectors on the Klean Harness System are color-coded for ease of use, and none of the components are hard-wired. Our system has four proximity interlock switches with plug-ends that integrates with Marshall Excelsior products. If you ever experience a problem, we can walk you through a series of simple troubleshooting steps so you can make your own repairs and get back on the road. Need a new part? We'll send it to you in the mail, and you can plug it in yourself.

Consistency Throughout Your Fleet.

Using the same system maintains consistency across your fleet. With components in a similar place on every truck, system repairs are standardized, eliminating guesswork and confusion. Whether you're retrofitting or buying new, the Klean Harness System is a way to simplify your fleet and save time, effort, and money over the long term.

Enhanced Safety.

Our Switch System comes standard, allowing you to turn on switched outputs automatically.

  • Automatic functions can be programmed directly into the KSC Switch System, allowing you to avoid the complexity of additional junctions. For example, the KSC Switch System's program can automatically turn on your backlights when you switch to reverse.
  • The largest percentage of driver injuries occur when getting into and out of a truck. Our auxiliary switch pack mirrors the cab, so you can operate lights and critical systems without the need to go back and forth from your cab.
  • If any safety interlock is interrupted, the parking brake can't be disengaged—but an interlock indicator can tell you before you're back in the truck, preventing pull-away issues and additional driver risk.
  • A standard BASE Engineering system allows you to shut off your truck and close all valves in the instance of an emergency, the Klean Harness System directly plugs into the BASE system, eliminating wire splicing.
Interlock Indication System

Optional interlock indication system to let you know if any of your ontruck interlocks need to be addressed before you get back in the truck. Plugs directly into the harness.
