No, use the Tach output line from your trailing coils. Should be a yellow wire with a female bullet connector on it. Run a wire from it to your RPM input on your AVC-r.

that simple.

If you are running the stock coils that is the easiest way to get a tach output.

It could work, but the Tacho output wire is there, just use that and you'll be fine.
