I've got a few of these HEI tach harnesses made up for use on 78-up trucks using a spade type fuse panel. Any factory GM tach cluster for use in a truck with HEI is suggested to incorporate a filter to help smooth out the voltage signal to the tach from the HEI coil. To my knowledge nobody makes a correct style replacement tach harness for our HEI equipped trucks so in my recent builds I've decided to offer one. Price is $109 per tach harness if anybody is interested!

If you need one for a 77-older truck, message me about it so I can make sure you get the correct style leads....fuse panel lead is different as well as the ground terminal.
