Ive been having trouble finding a tachometer it would be great if you could send links to where i could find one it would be very helpful.

 

I talked to a guy with a monster first gen sled puller and his goes to the harmonic balancer or something like that

 

ISSPRO R8912 Magnetic Tach Sensor-Geno's Garage think you might have to use the isspro tach with this sending unit since it has 2 wires instead of the normal 1
