4.3L (2014 and previous years) V6, 5.0L/5.7L/7.4L V8 engines are only covered by this procedure. Firstly, remove the engine cover. In addition to that, you can separate the air intake duct or resonator from the throttle body if you still need more space to work on your vehicle. On the right side of the manifold's intake is a bracket wherein ignition coil is also mounted and aside of which there is ICD module or ICM in 4.3L V6 engines (2014 and previous models) as well as in 5.0/5.7L V8 engines. The ignition coil and mounting bracket for the ICD module (or ICM) that are used on 7.4L V8s are nearly identical to those used on the smaller V8s and V6s; however, they are positioned behind the distributor at the rear of the manifold. If you want to replace an ignition control module on most of these engines, you should try removing it without dismounting an ignition coil mounting bracket from an engine block. However, if it is easier for you to remove them together, you can take out a control module along with a coil and mounting bracket as a single unit; otherwise, just detach it from a bracket or leave it attached to other parts of your car's ignition assembly till further steps are taken care of. Afterward, unplug all electrical connectors from the ignitions control modules before proceeding any further with repairs on this part of your automobile's engine system-this will help protect both yourself and anyone else who might be working nearby at this time; additionally, always be cautious when handling any such devices because they usually have very high voltage levels inside them which can easily electrocute someone even when they appear harmless externally like these small black boxes here which were used as examples above. Finally, remove the ignition control module mounting screws and take the module off of the coil/module mounting bracket. Now put everything back together again just like it was before but this time install that heat sink too otherwise this will not work correctly even though you've got a new one there now.
