I've been doing some work on my 88XJ 4.0L and discovered a frayed wire coming out of a wiring bundle under my intake manifold at about the level of the 02 sensor. The stranded wire appears to be stainless steel and shielded? Does anyone know what this wire is for? All my sensors are hooked up so it can't be a sensor wire. I thought that maybe it was a reinforcement wire for the wiring bundle, but the shielding around it rules that out.
