Awhile back I read where somebody added some type of electronic tach to their sled. Do not know the name brand of the tach and I think that they were only dealing with two wires.

I will be putting an Enticer 250 together for some vintage oval races and would like to add such a tach to the sled. Does anybody know of such a tach and how the are hooked up ?

Thanks for the help .....................
