Where in the 2001 vw jetta shaft speed sensor located in?

I've been trying to locate the shaft speed senor and could not find it can anyone please help.Where in the 2001 vw jetta shaft speed sensor located in?There are two electrical harnesses on top of the transmission housing. The one closer to the shift tower is the reverse light switch, and the one closer to the firewall is your speed sensor. You will most likely need to remove your airbox and battery to get easy access to it.
