Detailed Product Description

The Handy Pack HP4390 pigtail and socket assembly is intended for technicians and do-it-yourself repairs that require a dependable replacement MAP sensor connector. Its four-terminal layout and rectangular shape match common GM sensor wiring needs across a wide range of vehicles, including Chevrolet Astro, Blazer, Silverado 1500, Tahoe, GMC Safari, Sierra 1500, and Cadillac Escalade applications. The HP4390 part number is also a useful reference when searching for a GM MAP sensor connector pigtail or socket assembly.

This connector is especially relevant for GM trucks, vans, and passenger cars where connector damage can trigger drivability or sensor communication issues. If you are replacing a worn MAP sensor plug on a Chevrolet S10, GMC Sonoma, or Pontiac Grand Prix, HP4390 provides a direct repair path for the harness side of the connection. This part cross-references common GM-style connector repair needs for the same application.

What It Helps Fix

• Broken MAP sensor connector housings
• Corroded or heat-damaged electrical terminals
• Intermittent sensor signal caused by poor pin contact
• Damaged wiring at the sensor plug
• Failed harness-side connector repairs on GM vehicles

Installation Notes and Tips

Use proper crimping tools and follow standard electrical repair practices when splicing the color-coded leads into the vehicle harness. Verify terminal alignment, wire routing, and connector seating before clearing any diagnostic trouble codes. For best results, compare the original connector shape and terminal layout to the HP4390 before installation.
