I have installed a MSD 6014 to an LS1 in a sprintcar & I have hooked up the wiring as per the MSD instructions. The tacho is not working, but when the tacho is installed to a another engine with an MSD6010 unit it works correctly. The Tacho that i'm using is a Tel Tac pro & checked the wiring harness to the tacho & all correct.
Have read that the MSD6014 tacho output is a square wave which is the same as the MSD610. So I can't understand why it is not operating with the engine running or send a signal on when the key is turned on....
As anyone else come across this problem of a Tacho not working on a MSD6014.....
What pin should the Tacho wire be in for the plug from the MSD box?
As I can check that its int he correct location & also what is the pin location for the matching harness?
