Re: Sport comp monster tach = smoke from hei!?!?!?!?
Do you have the green wire connected to the TACH terminal? It is the one on the front left side of the disbributor cap when looking at it from the driver side fender.
Really the only wire you need to go outside the car is the green wire. The red can get a female spade connector and plug onto the fuse block beside fuse labeled IGN. The black wire and get a ring terminal and ground to the metal dash frame. You may see some instrument grounds already there between the steering column and e-brake. The white can be left disconnected until you figure it out, then it can just be tapped into the gray wire feeding the instrument lights.
With the key on and car off, the tach should immediately go to zero. When the car is running and then shut off, the needle will stop where it was when power was killed completely usually around 700-1000 RPM since it's an air core meter.
