    K O E O Engine Light..

    My buddy told me to do this since I cant find an OBD 1 code reader anywhere.. But Does anyone know how to trip the KOEO.. (key on enigine on) or I think its (Key on engine off)
    plug so I can make the check engine light flash and find out whats going on under my hood

      what year is your car? 88 and older cars do not have a CEL light.... NO CEL light = NO codes with out some sort of code reader/scan tool.

              The 1988 Grand Marquis has a check engine light wired into the computer. It will flash trouble codes when put into self test mode.

              Anything older than those two years doesn't have a check engine light hooked up to computer.
              As for the towncar. I know the 89 has one... Ground the single wire pigtail and go mang...

                  Interesting. We have claims of 88 Grand Marquis having them, and not having them. Mid year bs perhaps?
