Welcome to Allpar! I would personally recommend just replacing the sensor with the OEM style. If you think about it, the sensor has lasted 22 years before wearing out, so if you replace it, you should get at least another 10 years out of the OEM style sensor, which puts the truck at 32 years old. This is not a common failure part, and I think you're going to be looking at more trouble trying to go with an updated sensor than simply putting in the old style. Just because it can be upgraded doesn't necessarily mean it's a good idea to do it. Of course, all of my electronics projects seem to end up letting that grey smoke out, so I'm naturally kind of wary of anything in that vein... If you do try to do it, you will be making a pioneering effort, this is the first I've heard of anyone trying to attempt this. Best of luck if you do decide to do it, and keep us posted!
