I needed a tach to tune my truck and get the RPM at idle where I want it. The OEM connector did not have a tach wire. I could have added a wire, but I would have needed to modify the existing connector and I didn’t want to do that. This connector plugged right in. It fit perfectly. Once I test for the pigtail I spliced the factory wire and ran the tach wire into the cab and installed the tach. For the price this is a great product. And you get an extra pigtail. The tach is accurate and the pigtail was very easy to install. Review: Great price - Great product perfect fit and good quality materials ## Features - Precision Fit: Engineered to seamlessly connect with HEI distributor systems, this pigtail wire harness ensures proper alignment with Chevy 350 and other GM V8 engines. The molded connectors match factory specifications for vibration resistance - Heat Resistance: With silicone-insulated wiring rated for 300°F+, this GM HEI 12V pigtail withstands underhood temperatures that melt standard harnesses. Ideal for desert climates and high-performance applications - Secure Connection: The HEI distributor pigtail features brass terminals with precision 0.1mm tolerance to prevent loose contacts - a common failure point in cheaper alternatives - Color-Coded Wiring: Red/blue 12AWG conductors with clear markings simplify installation for DIYers working on 170072 replacement projects - Dual Pack Value: Includes two harnesses for multiple vehicle repairs or keeping a spare - because you never know when your buddy's HEI system might need emergency help ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0G328N72D | | Best Sellers Rank | #306,534 in Automotive ( See Top 100 in Automotive ) #1,473 in Automotive Replacement Electrical Wiring Harnesses | | Date First Available | November 20, 2025 | | Item Weight | 1.12 ounces | | Manufacturer | AXGSRV | | Package Dimensions | 3.97 x 2 x 2 inches | ## Images ![HEI Distributor Pigtail Wire Harness 2 Pack Tachometer Connector and 12v Battery Replacement for RV Chevy GM HEI 170072 - Image 1](https://m.media-amazon.com/images/I/61DpZvXQdNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great, easy install *by L***. on February 23, 2026* This HEI pigtail works great.
