Porsche Repair: 944 quirks continued, yellow blues, blade type

Question
Hello dave.
Ive had the flu and it has brought on some ambition in me for some reason. I have not much progress to report but do have some info. It turns out that the harness with a diode is just a splice. The wires in it are blu/blk, blk/blu(this was the spliced one), wht/prp, and blu/yel. I decided to take a look behind the fusebox and a bit of another rat's nest emerged. After tracing the wires, most of it ended up being fine, just pointless rewiring. There were 3 wires unplugged, though. 2 ended in a connector (which I couldnt find the female end to), and they were both brown, 1 having a black stripe. The other was a smaller red wire with a white stripe and a female blade type connector. Anything sound familiar? About the blower relay, is it different from the A/C, because the A/C fan blows loud and proud, no problems (just out of refrigerant). Also my owner's manual doesnt look like it has a relay for the heater/blower but again maybe i'm wrong. Anyways I hope I've given you something to chew on, otherwise my hour or so upside-down in my car was in vain. Thanks!

Answer
I just know anyone recovering from the flu by laying upside down in a 944 would never do anything in vain.  

Unfortunately, none of the wiring color combinations even comes close to my diagrams.  I went through two years checking for your colors and found nothing definitive.  Lot's to chew on, nothing tasted good yet.

Here's a repesentation of the notes I made, perhaps, you'll get something out of this:

--brown/black...alarm?
--blue/yellow...could this be yellow/blue,,,there are more yellow/blues than blue/yellows?  Also could this be blue/white?  There is a blue/white connected to a diode.
--red/white...could be to rear window de-fog relay, or seat belt switch, or seat belt warning relay.

According to my references there definitely is a separate blower relay, but of course my references keep talking about this mysterious additional fuse box...you're sure you haven't got one under a seat or a hidden door????

Tell me more when you have time.
