need wireing diagram for 01 sport

im looking for wireing diagrams for an 01 cherokee 4dr 4x4 4.0 auto. i need to find out what color the speed sensor wire is coming from the transmission computer and going to the sensor it self. also need to know where the trans computer is. i think it is under the center console but im not sure.

The trans computer is under the dash. The computer you see under the center is the ABS controller. You didn't say which speed sensor there are two.

Input sensor signal is RD/BK, and the ground is VT/LG
Output sensor Signal LG/WT, and ground is DB/BK

im not sure which one i should use. i need it for my pioneer navigation/dvd deck. the install instructions are pretty vagueit just says connect to the speed sensing wire.
