Brown and black
Blue and brown

Not sure how to figure out what they're for based on the colors

Maybe it's for manuals. Like a clutch pedal switch or something?

Looks like you were right

Signal 1 (brown/black): Ground
Signal 2 (blue/brown): This signal is triggered when the clutch pedal is depressed just slightly--it goes to DME for cruise control, idle-up such as when you push in the clutch to prepare for take-off, etc.
Signal 3 (purple/yellow): This is +12V supply for the clutch switch
Signal 4 (blue/black): This signal is triggered and goes to +12V only when the clutch pedal is fully depressed--it goes to CAS for clutch interlock.

Okay good. Knowing exact wire colors helps out a little bit as they have certain functions sometimes.

So when looking at the clutch switch I had to look at multiple ones. I'm fairly certain crystalworks is correct. Seems to make sense as given the location.

BR/SW -- Ground Electronic
BL/BR -- to DME
VI/WS-- 5A fuse
BL/SW -- to EWS

Wow you guys rock! Nailed it...
Any way to know from the diagrams if the 12v supply has constant power or only when the car is on?
I can't test it right now unfortunately as my battery is out for the moment.

If anyone is up for another challenge..
I cut off this connector from the trunk somewhere, do not remember where it went, but remember it was not connected anywhere do I deleted the wires.

Kept it out of curiosity to maybe figure out one day what it's for

If you look at the previous diagram picture fuse F39 is powered via Terminal R = ignition switch pos. 1.

Hey Clavurion...where in TIS did you find that? That is very useful and I tried finding it myself to no avail.

That can be found in original WDS.

The second connector for sure is for the speakers wiring.
Usually the blues go to the Mids, and the yellow is for the tweeters.


Just off the top of my head - I had to resolder my whole setup after a disaster with a failed Eonon install, since I have the DSP amp

Someone a little more knowlegeable will help me out on this, I'm sure...
