  • Automotive-grade construction

Pin Configuration / Wiring Diagram:


[ 87 ] Output (Load) | | [ 30 ] Power Input (Battery +) [ 86 ] Coil + (12V Control) [ 85 ] Coil – (Ground)

Pin Functions:

  • Pin 30: Common power input (battery supply)

  • Pin 87: Normally open output to load

  • Pin 85: Coil negative (ground)

  • Pin 86: Coil positive (+12V trigger)

Technical Advantages of Large Output Pins:

  • Increased conductor cross-section for higher current capability

  • Reduced contact resistance and voltage drop

  • Improved heat dissipation during sustained loads

  • Stronger mechanical connection for heavy-gauge wiring

Typical Applications:

  • High-power cooling fans

  • Winches and DC motors

  • Auxiliary and off-road lighting

  • Heaters, compressors, pumps

  • Power distribution and battery systems

Please check fitment before ordering.
Vehicle parts can have variants even within the same model and year. Compare the listing photographs, plug/connector shape, dimensions and part numbers where applicable.
