Assuming you have the right size hex drivers to remove the knobs from the pots and the pick-up selector, once you carefully detach the connectors with the pick-up leads from the preamp board, it should be pretty easy to detach the whole electronics assembly from the bass and send that to the Mothership. (Mine took considerably more time as it seemed like the owner before me had used permanent Loctite on the set screws for two knobs, so I ended up having to saw through them.)
I would recommend having the Q switch replaced with a 3-way, in addition to the pan control.
