I will TRY to describe what they look like... there are sensors located at each wheel - I have seen them listed as ABS speed sensors. On the rear, the sensors are located just above the parking brake cable on the axle flange. There is a little black tube coming out of it which shields two wires - one black and one white. Each sensor is secured by one hex head bolt through a silver mount. You will have to clean up the area to see that the mount is silver though. Check junkyarddog.com and wait up to a week for someone to reply to your needs - if any junk yard in the nation has it and is registered with the service they will email you saying they have what you need. The Trooper uses the same sensors so search using that if you have no luck with the VX sensor search.
