GT3 strapped to our dyno ... can't find ignition source???
 

This may seem like stupid question, but we have GT3 strapped to the dynojet (PCA dyno day today), and we can't find a source for the ignition signal the dyno needs to make a run!!

We found 2 leads on the left side of the motor that looked like they would work, but we are getting no signal. The ones we found were labeled "2" and "3". Any other suggestions?

Thanks,

Russ

It's generally easiest to tap into RPM-signal wire going into tachometer.
