Anybody out there able to provide instructions on how to switch over from an idiot light/fuel gauge('70 GS 455) to a gauge cluster with the temp. and oil pressure gauges? Also, what is needed to be changed in engine bay? It looks like there is some type of sending unit on the engine currently (blue wire attached) which I supppose trigers one of the dash lights...will this need to be replaced and any ideas on where sending units can be obtained? All help appreciated. Thanks...
