Waltco EM-Series Electrical Option Assessment: Dual Controls, Shut-Off Switches, Remotes, and Safety Features

Why Electrical Options Matter for EM-Series Liftgates

The Waltco EM-Series is built for high-volume, dock-to-ground delivery—but how you control the liftgate is just as important as the lift itself. With available dual controls, handheld remotes, and cab shut-off switches, operators can manage the gate more safely and efficiently. These options also help lift gate fleets meet security and DOT compliance requirements.

Choosing the right electrical setup isn't just about convenience—it directly impacts operator visibility, workflow speed, and safety in busy delivery zones.

Overview of Standard Electrical Setup

Every EM model by Waltco includes a basic switch control system mounted near the platform area. It connects to the hydraulic pump unit through a control cord, typically routed through a grommet in the pump enclosure.

→ Source: EM-Series Install Manual, p. 20–21

Components:

• Standard raise/lower toggle switch
• 150A circuit breaker at the battery
• Dielectric grease applied at all terminal connections
• Grommets to protect wiring

Installers must ensure cable tie-downs keep wiring away from:

• Exhaust system
• Brake and fuel lines
• Sharp edges

This standard setup forms the foundation for all optional electrical upgrades and should be installed carefully to prevent future service issues.

Option 1: Dual Control Switch Kit

Waltco liftgate control switch 80000437 is a dual switch offered for the EM series.

On Waltco liftgates, the dual controls for the EM series allow the operator to raise or lower the gate from either side of the vehicle—particularly useful for curbside or rear access depending on the dock setup. This is one of the most popular options for routes with frequent tight maneuvering or one-person delivery teams.

Features:

• Two 10–15 ft. control cords
• Adapter harness for pump unit
• Optional thermal wire adapter blade

Installation Notes:

• Switches must be mounted with full platform visibility
• Use a ½” hole with protective grommet to run the cord through truck walls
• Use dielectric grease at all connectors
• Secure using ¼” self-tapping screws

→ Install details: p. 47 / Adapter harness diagram: p. 47

Dual controls reduce the need to climb around the truck body to activate the lift, improving both efficiency and safety.

Option 2: Handheld Remote Control Kit

Waltco remote switch kit 80000430 is a handheld remote offered for the EM series.

This Waltco liftgate switch option allows operators to move with the lift while maintaining control—ideal for solo drivers or when visibility is limited. The corded remote gives you freedom of movement without sacrificing the reliability of a wired connection.

Features:

• Durable hand-held toggle switch with 10 ft. coiled cord
• Trailer plug/socket included
• Mounted socket at rear corner or side panel

Installation Notes:

• Drill mounting holes using included template (1¼” main + two 7/32” pilot holes)
• Socket wires:
• White = Raise
• Black = Lower
• Green = Power
• Connect to the dual control adapter harness (same as dual switch kits)
• Match male/female connectors carefully
• If the motor lacks thermal wires, use the adapter blade

Remote control options are especially useful when managing large or unstable cargo, where staying close to the load is critical for safety.

Option 3: Cab-Mounted Shut-Off Switch

Waltco liftgate cab shut-off switch 80000827 is offered on the EM series.

A cab shut-off switch prevents unauthorized use of the liftgate while the vehicle is unattended. When toggled off, it cuts power to the control switches at the rear. This feature is ideal for overnight parking or depot situations where access control is a priority.

Installation Overview:

• Mount switch in a visible, easily accessible location in the cab
• Route the green 16 ga. x 40 ft. wire from the motor solenoid to the switch
• Use bullet connectors and fuse line to tie into battery circuit

Important: Always use heat-shrink tubing and grommets when passing through any metal surfaces.

→ Diagram and wire routing: p. 49

The shut-off switch adds an extra layer of control and is particularly valuable for fleet managers seeking tighter security policies.

Option 4: Pump Theft Deterrent System

Locking Pump Cover Kit

→ Source: EM-Series Install Manual, p. 48

This optional cover encloses your Waltco liftgate pump unit, aka your Power Unit, and allows a padlock to be installed. It helps protect against unauthorized operation or tampering in public parking lots or overnight depot storage.

• Lock bar is included (padlock not provided)
• Welds to the pump housing

→ Visual diagram: p. 48

Simple but effective, this upgrade is well-suited for operations where vehicles are staged outside and left unattended between shifts.

Related Electrical Accessories

Waltco provides additional power and wiring options to support extended-length vehicles and trailer configurations. These are particularly helpful for installations where battery access is farther from the pump enclosure.

Wiring Kits

• Tractor wiring kit
• Trailer wiring kit (single and dual pole)
• Higher amperage cable options (150A, 200A)
• 50 ft. long cable option for extended frame trucks or trailers

Make sure to pair these accessories with the proper fuse and breaker sizes to maintain safety and warranty coverage.

Safety Considerations

Waltco provides very clear electrical safety guidance in its installation manual. Whether you’re installing a basic switch or a full dual-control setup, the following best practices apply:

• Apply dielectric grease to all terminals and battery connections
   → Install Manual, p. 21–22
• Always protect wires using grommets when passing through sharp-edged panels
   → Install Manual, p. 20–21
• Secure cables away from hot, moving, or sharp components
   → Install Manual, p. 22
• Never operate a liftgate with exposed, frayed, or corroded wiring

By following these standards, you help prevent electrical shorts, downtime, or operator injury.
