How do you change the module?

Remove 2 bolts. LOL mine is located on the throttle body

you can't

the module is under the coils, unplug the wires, unbot all three coils and unbolt the module. Make sure to use plenty of dielectric grease for a good ground

If this is a 1985 with 318 V8 it is mounted on the side of the aircleaner, remove a few screws to replace it.

lots of fun....locate the coil pack usually on the front of the motor towards the bottom.take off the coil packs and the module is underneath.under the exhaust manifold.
