LCR LH C-Pillar Wiring - Pin Out

Good evening, all,

I'm currently replacing the 3 x wiring connectors (black, brown, pink) in the left C-pillar of my 2003 LCR due to corrosion, probably due to a leaky windscreen washer pipe at some time in the past. I've got the SEAT repair wiring parts (thanks to the guys at SEAT Worcester), and have successfully replaced both halves of the pink and brown connectors.

I need help with the wiring connections for the black connector, as two of the wires have corroded completely, meaning I've no reference for the correct connections.

Does anyone have a picture, or the correct wiring diagram, for this connection? In return, if anyone's interested, I can post the P/Ns and a few pics?

Thanks in advance!

The only place to have the full wiring diagrams for these cars is 'Elsawin'. I lost my copy when my old laptop died, but there are copys on ebay available. I'm not sure if they are strictly legal as i think the software is officially owned by VAG group. I haven't tried the new version yet, but the old version was fine and contained all wiring diagrams for every connector.

Thanks Matty
I have actually found some pictures I took a few weeks ago, when I originally looked into this issue. At that point all the wires were still attached.
Pin 3 of the black connector in the C-pillar has a Brown with Black tracer on the car side of the loom, but a Blue with Green tracer in the tailgate side of the loom.
Every other wire matches from side to side of the connector, if that makes sense.

Yeah some of the wiring in these cars is so confusing, i had a nightmare trying to work out the colour codes for the fuel flap solenoid last year. Glad you got it sorted anyway buddy.
