It's about 2 inches by 2 inches black and there's a connecter usually white that connects to it.
If it is like the 93 Mazda 929 it is inside the car on the passenger side under the carpeted molding on under the dash opposite of the center console big silver box with three large connectors it is held in with 3 10 mm bolts
it may be under the seat where most control modules are
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.
If you mean the Power Control Module, it is located on the passenger side of the engine compartment, along the upper edge of the firewall.
The airbag fuse is an integral part of the airbag control module and is not a replaceable part in itself. The airbag control module must be replaced.
1994 - 2005 Mazda Pickups Repair Manual lists a Power Control Module (PCM) located on the passenger side of the engine compartment, along the upper edge of the firewall.
"ECM" Electronic Control Module (Under front seat or behind dash).
The 1994 Ford Aerostar ignition control module is located on the firewall in the engine compartment. The ignition control module will be on the drivers side of the firewall.
It doesn't have a body control module.
Under the steering wheel at the very left at the bottom
Never mind, found the answer. Did not find how to delete my question...
I have a 1994 C1500. The spark control module is located in the cab, on the passenger side, above the heater blower. You can access it through the glove box by removing the inner liner. JFK
