I was afraid of having to wire in a new sending unit, unless of coarse its only a wire or 2. Is there any way to convert the electric speedo gauge cluster to work with a normal cable drive? Can I maybe replace the internals and what not in the electric cluster with the internals of my old cable driven cluster? WHat would happen if I just ran my cable into the electronic cluster, would it get fried or something or just not work at all?
