Challenging electrical issue with 911 SC

Hi guys:

My '79 911 SC has a 12V draw that I cannot track down.

-Trunk light disconnected for testing.
-With the voltage meter checking charge at the negative battery post and ground cable, I've removed all fuses and relays individually and found no change in draw.
-I've disconnected the cable at the starter and find no change in draw.
-Nothing is "on" that I can find. Interior lights work, but door switches are not functioning. I have one loose wire -driver's side- for the interior light door switch, but get no voltage reading there.
-Note: I have two red wires running to my positive post on the battery and the car will not start without those attached. They do not appear to be stock.

The car had AC and an alarm that were removed after I bought it. Car runs beautifully with the exception of the draw. Everything works.

Does anyone have any insight? Electrical is not my first language at all and I'm stumped.

Thanks.
