Installation Notes and Tips

Verify the connector style, terminal count, and compressor-mounted location before installation. This part uses a clip-in, no-thread mounting style, so the compressor port and retaining method must match the original switch design. Confirm the vehicle’s low-off pressure specification and compare the original switch configuration to the replacement before service.
