Sure there is a stock module / box. The location is on the passenger side fender wall. It is located near the bottom of the inner wall in front of the strut tower. It has an aluminum heat sink with large fins and has the plug installed in it. The module uses the aluminum to cool itself. These used to be installed on the distributor but Ford knew they had an overheating issue, so it was relocated away from the engine. You can use the harness at the coil for the MSD box. You need to use the + wire for the coil and follow those directions you get from MSD. They do sell a plug n play adapter to make it easy if you do not want to hack into the factory wiring.
