Where do you connect the wires on a factory tachometer in a '65 Chevy Impala SS with 327 4spd trans?

The pos wire to the dist side of the coil and the neg wire. Gray Lamp wire to lamp plug at the top of the fuse box in the lamps plug. The top hole is for a light with a grey wire like your dash lights,the connector right below it should have a brown wire to your coil or hei(tach side) .

The last lowest connector is a black and pink wire that goes to power and connects to the fuse box.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
