Connecting a Cat Dozer Blade to an ASV Posi-Track: A Clear Wiring Guide

[MikePhua]

Introduction
When you mount a Cat-style dozer blade onto an ASV Posi-Track loader, the difference in electrical connectors can be a source of confusion. Cat uses an 8-pin connector, while most ASV models use their own 8-pin setup with different pin assignments. Fortunately, the wiring is straightforward once you understand the pin mapping—get it right, and your dozer blade functions smoothly with tilt and angle control from your ASV's joystick.

Key Wiring Compatibility

• Cat-style blades use an 8-pin connector.
  
• ASV machines also use 8-pin connectors, but the pin assignments differ.
  
• According to Skid Steer Genius wiring documentation, the ASV 8-pin layout works like this:
  • Pin A is Ground
    
  • Pin B is Bottom switch (left stick)
    
  • Pin C is Right switch
    
  • Pin D is Left switch
    
  • Pin E is Ground
    
  • Pin G is Top switch
    
  • Pins F and H are seat switch jumpers (ignored for blade control)
    
• The Cat-style harness wires are arranged this way:
  • The black wire goes to Pin A
    
  • The white wire goes to Pin B
    

Pin Mapping Summary

• Black wire connects from the blade harness at Pin A to ASV Pin A (Ground).
  
• White wire connects from the blade harness at Pin B to ASV Pin B (Bottom switch).
  

This simple two-wire mapping allows the blade’s tilt function to work using the ASV joystick’s bottom switch.

Installation Steps

1. Prepare the system and identify pins: unplug the dozer blade cable, note the black wire at Pin A and the white wire at Pin B on the Cat connector.
   
2. Map wires to the ASV connector: connect the black wire to Pin A (ground) and the white wire to Pin B (joystick bottom switch).
   
3. Secure the connection: use a Y-adapter or splice kit if needed, then secure wiring along hydraulic hoses with zip-ties.
   
4. Test the blade: reconnect, then use the joystick side-to-side or bottom switch to confirm tilt functionality.
   

Additional Tips & Considerations

• Intermittent vs. continuous flow: for a dozer blade, intermittent auxiliary flow is usually sufficient. ASV loaders such as the RT-30 can control this with either a toggle switch or dash switch.
  
• High-flow attachments: some newer Cat D-series blades need extra wiring (for example, a sense wire via pin K or J). Mismatched wiring between brands can blow fuses.
  
• Use quality adapters: adapter harnesses from suppliers like Skid Steer Genius simplify the process and reduce wiring errors.
  

Summary
By wiring the Cat blade’s black wire to ASV Pin A (ground) and the white wire to ASV Pin B (bottom joystick switch), you retain tilt functionality. Adding a Y-adapter and securing wiring ensures reliable performance. If additional blade functions are required, such as angle control or automatic hydraulic flow, an advanced harness or adapter may be needed.
