oldtime_ironman, thank you for your info this does help me some.
Que89YJ...I actually did come across one of your threads before when you were discussing this with brentd711. Actually that is how I knew about the 91 Cluster. However I'm still a little confused, and maybe because I'm not real certain on the components and setup with the VSS.
Correct me if I'm wrong guys...But the vehicle speed sensor (VSS) is a sensor that will connect into my current speedometer port on my transfer case with no modification. Then coming out of that VSS is the speedometer cable that goes up to my speedometer and one signal wire that I will need to splice so that I can run one to the new 1991 speedometer gauge (Which I will have to get) and one to the ECM. Is that correct or did I mixup something with the wiring. (or can I keep my existing speedometer that I have now and there is no signal wire that has to go up to the dash, only to the ECM which makes more sense to me) Also were or how do I tie into the ECM? Thanks!
