My 40+ yr old original temp gauge is erratic( works fine one day then goes on crazy mode and back to OK status), I want to keep the original gauges and not to mess with old electronics , the plan is to add a secondary mini temp gauge , there is an extra spot on the LS1 engine to do this, gauge/adapter on hand. But this mod will be l done at a later date, for now I will place this temp/digital/gauge as a quick fix in order to monitor the temperature , I will place the probe on the returning radiator hose ( no butchering, the probe all it needs is contact) and the small digital gauge ( 3''x1'') under the driver's side cabin vent, that will keep me informed >>>>
