I have a MSD 6A on my 84. Tach wire goes on side of MSD unit where there is a tach pick-up outlet. Also, get rid of the tach filter. Worthless.

The tach filter should be bolted down on the manifold near the distributor. If it not there then someone did the favor of getting rid of it.

Buy the MSD install harness for your car. It's plug 'n play.

I did but the only wire not being used is a brown wire that is doubled up....no tach wire....the msd instructions don't really say what to do with the tach.

I mounted my 6AL in the compartment behind the drivers seat and ran the harness behind the rocker panel. Once its installed you can't even tell. I used the MSD jumper harness and had to splice one of the wires and remove the tach filter and everything works perfectly. I can take a pic and email it to you if you want.
