for my door latch mechanism, i'm using the setup used in minivans from around 93-2000 that also has the power lock setup built in. i have a bunch of those handy, and they also fit my bus plus the wife's car. they are a pretty compact unit and will fit the door area great. i also have the latch plate [the piece the latch bolts to on the door] fabbed for both doors. the suicide safety latches are the universal manual types, but i looked them over good, and i have an idea how to convert them to power using some imperial solenoids. what i meant with the statement about grouping the wiring together, i will be using several late model lighted switches ganged in a pod to operate these systems. the thing i haven't decided upon is weather to use a flexible harness to go through the door/door jamb, or use those brass contact setups.
