Re: Quick question about factory tach

The tach you got from LMC is a replacement tach for a tach cluster and not designed to work with your standard gauge cluster housing. It will take some considerable modifications to your cluster housing, a printed curcit, a tach harness, and repinning of your cluster plug for everything to work.
