DRL Module Failure – Symptoms

• Daytime running lights not illuminating at startup
• DRL warning light on dashboard
• One DRL inoperative while the other functions normally (connector fault vs module fault)
• DRL flickering at idle – intermittent open circuit at 15326614 connector

Excavator Throttle Switch – Why This Connector

Many excavator and construction equipment manufacturers source Delphi connector components for their harness assemblies. The 15326614 is used in throttle position switch circuits on equipment where the operator selects engine speed (low idle / high idle / work mode). A failed connector at this location causes:

• Engine stuck at low idle – cannot increase RPM
• Throttle switch not responding to operator input
• Fault codes on excavator diagnostic display (varies by OEM)

Frequently Asked Questions

Q: Is 15326614 a GM or Delphi part number?
A: 15326614 is a Delphi manufacturer part number. GM uses a different catalog number for the same connector in their service parts system. Cross-reference with your vehicle's service manual to find the GM equivalent if ordering from a GM dealer.

Q: Can this connector be used on excavators and construction equipment?
A: Yes. The 15326614 is used in Delphi-sourced harness assemblies on multiple excavator brands. Verify by OEM part number on your equipment's wiring diagram before ordering.

Q: What crimping tool is needed?
A: Use the Kent-Moore J-38125-6 or Delphi 12085271 ratchet crimper for Delphi Metri-Pack terminals.
