Throttle Switch Connector?????

[Brice Warnick]

I finally got the throttle off. I had to file the head off the phillips
screw that held the bottom of the switch.
The Audi switch part no. is 034 133 154F and the Bosch no. is 0 280 120
410.
My question is the throttle switch connector has 6 places for 6 contacts
but there is no contact in position 5 on the connecter. SEE PIC

Is this correct? Why is there no contact in position 5 of the connector?
