dropping my '94 northstar, and.. the wiring?

i'm prepping my engine for dropping it out, and i think i have everything under control - EXCEPT for the wiring! i'm disconnecting (and labelling of course) all the connections i can find. however, there's a big bunch of wires that seem to lead down under to the transaxle, and it's starting to get frustrating.

is there any way to make just a few simple disconnections, from both the dash in-car and the fuse boxes on the driver side wheel well?

what if i dropped the fuse boxes along with the engine? good idea? bad idea?

do i have to follow all these bundles of wiring to each individual harness and disconnect it all seperately?


any insight, advice, or other comments would be appreciated. thanks!
