97 E320 immobilizer issues
 

I have a 97 E320 doner car that I'm using the engine and trans from. I'm in the process of removing all the stuff I do not need from the interior side of the harness. Somehow something shorted and blew the 50A fuse on the K40 relay and after replacing it I have a crank no start issue with fuel pressure and spark. This is indicative of an immobilizer issue.

How can I reset the DAS/immobilizer? I have the key and access to the entire harness.
