trying to figure out my new car,lol . it has a msd 6 box,and msd pro billet dist. on a 350 engine and auto trans. its all in a 91 rs. anyways, they had wired up a aftermarket tach,on the dash, that didnt work when i got it, just trying to figure out which wire is the original tach wire.? so i can hook back up the original tach.the msd box has a "tach adapter" not sure what that is used for. it has 3 wires coming out of it. and they had a white wire from the main harness going into one of the 3 wires. if thats the tach wire, where would i hook it up to?? thanks alot.

There will be a slot on the end of the box that
will be the tack connection.

It takes a spade connector.
