Many owners of early boats have chosen to relocate the engine instrument panel up on the side of the coaming where the instruments were mounted on newer boats. Some owners report the original wiring harness connecting the engine to the engine panel is not long enough to facilitate the move, so this longer harness is required.
The original 8 pin push together plugs connecting the engine and instrument panel are a high resistance connection that often overheat and could cause a fire.
Always replace the original 8 pin plugs with the terminal strips offered below as "Engine Wiring Harness Upgrade Kit". They provide a physically more secure, low resistance connection that reduces unwanted heating.
