I am more worried about hood clearance with the typical top post disconnect. If you are worried about theft, memory and fire, there is a fuse bypass style. Hit the key and the fuse blows.
As far as learning, I doubt there will be more than 5~10 minutes of relearning you will notice. Not bad for a winter worth of not worrying about old wiring.
PLEASE Let me know if you find one that fits well!
