RUF tachometer install question
 

I had install RUF gauge set today, but the tachometer seem not working, but my original 930 tachometer work very good. It seem need a different signal.
The original is 4 pins, now is 7 pins.
Does any one know this? Really appreciate!

Thanks!

I would call these fine folks and ask before trying different combinations.
