This may seem a silly question, but I was thinking today, and perhaps I
read it in one of my books or in a post or something. But I have a GRT EIS
for engine monitoring, and was wondering about the tach. How do I hook it
up so it will read RPM. I know it is going to read engine RPM, but there
is no mag, does it use a coil? If so, which one?  Probably a simple
solution that I am missing, but I have drawn a blank. BTW, I have a Renesis with LS1 coils and an EC2.

Thanks...
