Help to identify a five wire loom
 

I am in the process of wiring my 86 911 Coupe which had extensive fire damage. I’m trying to identify a particular loom. The loom comes into the cabin area with a lot of the radio wires. I’ve gone through each diagram in the Bentley and the shop manuals and can’t figure it out. Black wire with blue is lighting so I believe something would have a light come on when someone turns on the parking lights. Any help would be appreciated. Here are some photos of the wire and where enters the cabin area from the firewall area.

The wire colors are the following:
BLK/BLU - lighting
BLU
BLU/WHT
WHT OR GRY/RED
BR/WHT

maybe instruments area? there may be opther instances of these colors, but first quick glance of the riagram I found:
Blu/Wht is used for the high beam indicator located at the top of the Tach.
Wht/Red is used on the speedo.
there is a blue on the intermittent wipers and also one on the power windows

It looks like a loom that is about 6 feet long and they are all together terminating together, so it’s something either in the passenger compartment or feasibly in the engine area, but I doubt that. What is the speedo thing you mentioned because that would be a possibility in the transmission area? If it only had a sticker that wasn’t melted off, that would make my leg easy with the part number.

Anyone?
