Erik, The former owner did what we suggest to all D owners; disconnect the door lock module. Your lock module can be found at M:07:02 fig. 32 refereed to as the impulse unit in your DeLorean Workshop Manual. This item has no connection to the other relays therefore the relay update kit will not effect the door lock circuit. To return your locking system to the original design and function purchase the Lockzilla.
