GM Tach hook up HEI system

What Are You Workin' On? image | posted by 77camaro

This is were the tach hook up is on a GM HEI distributor. There is a male spade where it says TACH under the plastic cap-You will need a female spade connector for your tach lead-solder the connection on tach lead and female connector-and just plug it into the distributor- feed wire up under the plastic cap Make sure you get it on to the male spade terminal-you could miss it and go along side of it- give the wire a pull and make sure you got it- GM made this an easy install port. The tack lead must be fed through the firewall useing a rubber gromet!! Hope this helps 77
