Here are the instructions from my tach adapter

According to everything, would it be ok for the output of the ignition relay be connected to the INput on the tach adapter.

 

Then the output of the adapter goes to the input of the ignition/coil harness?

autometer sells the exact same product, they emailed me back and I was right to follow the instructions.

 

Output of igniton relay goes to input of tach dapter, output of tach adapter goes to input of coil harness. You can also trace the power wire on the sr20 coil harness and tap it
