Where is the electronic control module located on a 91 Ford Festiva?
It's on the firewall, inside the driver compartment, under the carpet/floor cover, and to the left of the steering column.
I am sorry, I can't for the life of me figure out what you are talking about. Unless you mean an electronic MODULE. If that is what you mean, then there are several electronic modules on the vehicle. The main engine computer(PCM), the electronic ignition module, the cruise control, air bag module, even the radio is an electronic module.
