Why Install a Lift Pump Trigger Harness?
Many aftermarket lift pump installations require installers to tap into ignition circuits, wire in manual relays, or modify the factory wiring harness.
The Glacier Trigger Harness eliminates that guesswork by using the factory lift pump control circuit to activate the relay automatically.
Benefits include:
- Factory ECM-controlled pump operation
- Cleaner installation
- No wiring modifications
- Professional electrical connections
- Simplified aftermarket lift pump installation
- Easy future serviceability
Glacier Tech Tip
This harness controls your aftermarket lift pump—it does not power the pump directly through the factory wiring.
The factory ECM activates the Bosch relay, while the relay supplies power directly from the battery through the included fused 14-gauge power wire. This reduces electrical load on the factory wiring while ensuring your aftermarket pump receives a clean, reliable power source.
Note: You will need to supply the electrical connector that matches your specific lift pump, since different pump manufacturers use different connector styles.
Why Glacier Built It
Aftermarket lift pump installations shouldn't require cutting apart an expensive factory engine harness.
Glacier designed this harness as a true plug-and-play solution using quality components throughout, including OEM-style connectors, a heavy-duty Bosch relay, fused battery protection, and automotive-grade wiring. The result is a reliable installation that looks factory and is easy to service in the future.
