So I have a 89 YJ with a V-8 conversion with a non-working speedometer or tach. The speedometer cable is not hooked up to the tranfercase. Bought it that way. I noticed that the tranfercase looks to be from a later model Wrangler. It has the VSS connection. I have the old mechanical speedometer cable. The VSS connector/plug is missing. As I have tried to research the adaption of mechanical to digital, there seems to be a wide variety of options. I am trying to figure the simplest way to do so? Does anybody have any experience with this? Not sure why the previous owner did not complete the changeover. Lack of funding or some other reason. Everything else with the conversion was spot on. The tach I can explore later. Appreciate the help.
