how do u hook this thing up i used my tach wire from my coil and it still is not working can some one pleas help me

 

Did you get the regular or digital one?

 

regular one and i cant get it hookup

 

do you have an msd ? if you do and use the tfi harness, you need to use the wires off the harness... not the wires off the dizzy

nx should have a fantastic wiring schematic and instructions on their site. look for it
