Ok so i have a 93 civic coupe with a built obd1 gsr and m&w pro10 ignition with crane ps92 coil ... my question is I removed the factory coil and ignitor but now the blue wire that went to the ignitor is no longer connected to anything ... Where do i get my tach signal from for my factory cluster and shift light? And where do i hook the blue wire from the pro 10? Thanks guys the help is much appreciated

 

Blue wire is output from the pro10 that will go to your factory harness wire for the tach (which is also a blue wire).

 

You sir made my day! Ur the man!!

 

Glad to help, hope that gets it working for you...

I just did the pro10 setup as well recently and glad I did.

 

my pro 10 has been working flawlessly
