Default 1981 Tachometer

I searched the forums and I'm thinking my answer won't be what I want, but I want to make sure. I just dumped the stock distributor and installed a vacuum ported one. Now I have no tachometer, so is installing an older (non-electric) tachometer the only way to get it working again?

No. If you put in a HEI, check that you have the tach wire to dist. connected.

99% sure it was HEI, is this not the tachometer wire? There is no place I see for this wire to come out of the inside of the distributor. A friend who was helping me hooked the distributor back up so at the moment I am unsure if there is another wire left off.

The distributor is brand new, but I talked to a friend and think I now understand what is being said. I need to take the tach wire from the 4 wire packard and run it to the distributor? If this is right, then my follow up questions are which color wire is for the tach and to which wire does it need to be put to on the distributor?

The old one came out of a 1981 350. When you asked the first time, I just thought you were asking about the new one thinking it was used, sorry.

On a 81 the signal wire should be white.

The cable you have in the picture if the computer control connector for the 1981 and will not be used in the new Distributor.

I believe that the tac connector was the red connector that you removed and I saw in the pictures you showed me of the relay. If that is true, you can keep the red connectors.
