Works great, easy install
This HEI pigtail works great. 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.
