tach install

ive tried installing my sunpro super tach 2 but i just cant get it in need of help

 

Can you be more specific.

 

i have the switch set to 6, got the green wire hooked up to ignition coil wire, red to power wire from the radi and im still not getting anything.

 

Correct, but if you are running a msd box like a lot of people (me as well) the green will go into it, otherwise it won't read your rpm and will sit at 0

 

thanks got the tip im running with the msd and i pluged into that and it worked.
