To set it up, either use the hole in the end bracket and a drill bit, or better still, remove the exhaust and feel the lower edge is flush with the manifold when fully retracted.

So, when we set it up, aligning the marks or using the hole, we just set it to the position that the servo is in when we turn the ignition on (and the motor is off)?

I think the confusion comes from the workshop section saying that unplugging the TPS moves the servo to the position required for this setup, but when the TPS is disconnected, nothing happens (its in the same place as when the TPS was connected).
