Just switched out a gauge cluster with tach into a 1993 2wd 4cyl.....Only problem is....The tach cluster came out of a 1994 SR5 V6 truck.... If I had seen this was going to be a problem I'd kept on looking for a 4cyl tach... I probably could get my money back but not sure... IS there a way to overcome this problem other than replacing the cluster...???
