1968-1982 Corvette LS Gauge Components

Swapping an LS into a 1968-1982 C3 Corvette removes the distributor that a traditional tach was built around. The BRP Tach Adapter rebuilds that signal, and the Oil Pressure Adapter Fitting lets a traditional pressure sensor read the LS.

Will a shift light run from the same adapter?

Does BRP have an oil pressure part for an LS swapped C3?

Yes, the Oil Pressure Adapter Fitting, so a traditional pressure gauge sensor can be used on the LS.
