Re: 1990 electric instrument cluster/speedo

as you can see from the front view there is no difference but from the back there is no cable connection. the speedo gets its feed from #18 track on the 18 point connector. there are three feeds but two are just common. probably wouldn't be that tough to figure out how to re-arrange the connectors from a typical 81-89. I've rearranged a few it just takes alittle time. you could rearrangeand have the #18 track open and then add that wire'stand alone' into the system. where exactly that wire goes to down below your truck i have no idea. prolly NOT right into the tailshaft of the tranny. prolly into the ECM first ?????????? ,crossy
