Pinout Configuration
The Bobcat 7-pin connector typically has the following pin assignments:
- Pin 1 – Ground
- This is the primary ground pin, providing the electrical reference point for the attachment's system.
- This is the primary ground pin, providing the electrical reference point for the attachment's system.
- Pin 2 – Power (+12V or +24V)
- This pin supplies power to the attachment for electrical functions like lights, motors, and other powered accessories.
- This pin supplies power to the attachment for electrical functions like lights, motors, and other powered accessories.
- Pin 3 – Auxiliary Hydraulic Power (High Flow)
- For attachments requiring hydraulic power, this pin connects to the machine's auxiliary hydraulic system, either standard or high flow.
- For attachments requiring hydraulic power, this pin connects to the machine's auxiliary hydraulic system, either standard or high flow.
- Pin 4 – Hydraulic Return
- This pin is responsible for the return flow of hydraulic fluid from the attachment back into the machine’s hydraulic system.
- This pin is responsible for the return flow of hydraulic fluid from the attachment back into the machine’s hydraulic system.
- Pin 5 – Auxiliary Hydraulic Power (Low Flow)
- Similar to Pin 3, but dedicated to attachments that use low-flow hydraulics. This allows for smooth operation of less demanding tools.
- Similar to Pin 3, but dedicated to attachments that use low-flow hydraulics. This allows for smooth operation of less demanding tools.
- Pin 6 – Control (Activation or On/Off Switch)
- This pin controls the activation of certain functions, such as engaging or disengaging the hydraulic system or turning an attachment’s electrical components on or off.
- This pin controls the activation of certain functions, such as engaging or disengaging the hydraulic system or turning an attachment’s electrical components on or off.
- Pin 7 – Signal or Communication
- Used for two-way communication between the machine and the attachment, often providing diagnostic or feedback data on the attachment's status.

Bobcat machines can be fitted with a wide range of attachments that rely on the 7-pin connector for operation. Some of the most common attachments include:
- Augers: Used for drilling holes, augers require hydraulic power for rotation and electrical power for operation.
- Hydraulic Breakers: These attachments require both hydraulic flow and electrical signals to operate the hammering mechanism.
- Snowblowers: Snowblowers use hydraulic power to move snow and electrical power for the motor that operates the fan and lights.
- Trenchers: Like augers, trenchers require hydraulic power for digging and often need additional electrical controls for lights or safety features.
- Forks and Grapples: Attachments like forks and grapples use both hydraulic and electrical power to allow for lifting and grabbing tasks.
- Wiring Damage
- The most common issue with the 7-pin system is damage to the wiring. This can occur due to wear and tear, environmental factors (such as exposure to water, dirt, or debris), or physical damage during use.
