Wiring the RZ1 for External Power Detection

This guide explains how to connect external equipment such as PTOs, switches, or auxiliary systems to the RZ1 Vehicle Hub using the RZ1 Auxiliary Input Accessory. When wired to IN-1 (Yellow) or IN-3 (Brown), the RZ1 detects voltage between 9–24 V and records the signal as a digital input event.

What You’ll Need

• RZ1 Hub

• RZ1 Auxiliary Input Accessory

• Connecting tools and materials (e.g., butt splice connectors, cable ties, wire stripper/crimper)

Wiring Instructions

1. Identify the Power Source 

   • Locate a +12/24V circuit or output wire that becomes active when the equipment is operating.
   • Examples: PTO output, auxiliary light control, or push-button switch line. 
   

   Tip
   Use a multimeter to confirm. The wire should read 0V when inactive and +12/24V when active.
2. Connect the Input Line 
   • Choose one of the available input lines: 
     • IN-1 (Yellow) – Digital Input 1
     • IN-3 (Brown) – Digital Input 3 
   • Connect the equipment’s +12/24V output to the chosen input wire. 
   • Use a fuse tap, solder, or crimp connector for a secure connection. 
3. Connect the Accessory to the RZ1 
   1. Plug the RZ1 Auxiliary Input Accessory into the I/O port on the RZ1 Hub. 
   2. Ensure the connector is fully seated and locked in place. 
4. Connect Ground 
   • Connect at least one GND (Black) wire from the accessory to a clean chassis ground. 
5. Verify Operation 
   • Activate the connected equipment or press the switch. 
   • Using a multimeter, confirm the input reads 9–24V when active and 0V when inactive.
   • In the RoadEazy platform, confirm a Digital In 1 or Digital In 3 event appears.
