Locating an ignition module in a 93 Dodge Caravan?

[krazybob613]

The coils are driven by the ECM which takes signals from the crank and cam sensors / or distributor sensor depending on the specific engine model to calculate the spark timing. ECM's do not die often - the sensors are much more frequently the problem.

My brother's van has quit out on him, my brother in law whose a supervisor at Toyota has told him it's the ignition module but we can't find out where the things located. Any help would be appreciated. Already breezed the internet, found alot of stuff on the ignition coil which he's already replaced so it's not doing me much help. Thanks alot.
