Help Needed Jumping tach at startup? Not the CPS!

[trackspeeder]

Ordered it (F7TZ-7F293AA) from Ford for Monday delivery.
They call it a neutral safety switch or transmission range sensor.
Having it installed. Some things I just won't mess with.

But until then, starting it in neutral works just fine with a perfectly smooth idle.

Transmission range sensor is the current name for that part.
