I'm removing the entire wiring harness from a 98 WS6 and I cant figure out how to disconnect the harness leading from the drivers side interior to the drivers side engine bay. The pack is located on the drivers side firewall, near the brake booster. Pics of what I'm talking about are below.

From engine bay:

 

if its anything like the 3rd gen one in the passenger fender, that bulkhead is solid and does not come apart. the hole should be big enough to get everything on the interior side to come through

 

Yea I think thats the case.
