That should be VS for Vehicle Speed. It would come from the transmission or transfer case output shaft to the speedo meter.

Post up more information of your XJ especially the year. Someone will be able to help you.

The two square connectors I think you're referring to would be the transmission (solenoids and sensors) and the Neutral Safety Switch (also called the trans range selector switch).

Looking at the 97 and 99 FSMs, there should be a 3-wire connector for the VSS, with violet/orange (+5 volts), brown/yellow(ground), and white/orange(vehicle speed sensor). It's probably down at the sensor itself in the rear of the xfer case.
