anybody out there know what the two prong sensor is on the back top of engine block like directly underneath power steering cooler. I just installed a fresh 502 in my 88' Convincor, and have everything wired up ecept that one sensor? I bought the boat with a blown motor that was partially tore down. in the harness i have everything lines up and has connection except that one sensor. the sensor did come from the original block. any ideas?
