Does anyone have a diagram of the 42-pin connector (blue) that's next to the fuse box drivers side in a R53? I had to replace mine awhile back because it was corroded and think I may have installed a pin (or two) in the wrong place. After replacing this connector I have an issue of my wipers turning on after turning the ignition off. Also, the dash lights (mainly air bag light) will stay on and flicker. Only way to stop this issue is to disconnect the 42-pin connector every time I get out of the car. I have replaced the battery, checked the BC1 (completely dry and free of corrosion), checked all of the fuses in the car and under the hood.

Problem was caused due to a leaky sunroof drain so I fixed that issue. Initially the car would not turn off after removing the key from the ignition so I had to stall it to shut if off. I let the car dry out for awhile and replaced the battery. Issue seemed to go away. I then pulled the drivers side kick panel off to check the connectors (blue 42-pin connector was bad). There is still water underneath the carpet. I need to remove the carpet and soak up the water (any tips on this would also be appreciated).

I had a few pins break on the 42-pin connector so I replaced them. I need to get my hands on a diagram to see if all of the pins are in the correct spot. Attached are pictures of the connector I'm talking about.



Any advice would greatly be appreciated.
I need a diagram of what all of these cables go to.



I tried taking them out of the old connector one by one and put them into the new one.



You can see some of the corrosion on the black piece.

 

what ever happened to this I'm going through the same problem right now

 

I have a bently manual, let me look.

 

thank you I appreciate it.. I have everything else spliced up but I want to be certain ..
and I been looking at diagrams because I know those wires in the plug in my pic are exact how it came off and I cant seem to correspond it with anything

 

PM me your VIN. Ill send you the pin locations for X15 connector. They have different pins pending on options installed from factory

 

still no solution found this on youtube this guy Is messing with the same problem 12:50 he shows it

 

Can you look up mine too?

 

I figured out why my wipers came on when I turned the car off. I had two wires switched on the female side of the connector. The connector is called the X15 as SRICHS mentioned above. Here's the link for the connector and the wire diagram (with the colors).

The diagram doesn't have the actual colors shown but have the abbreviations. It took me a bit to decipher what they were. Below is a small key

RT=Red
SW= Black
GE= Yellow
VT=Violet
WS= White Strip
GR=Grey
BL=Blue
GN=Green
BR=Brown


I hope this helps everyone.

I'd start with a can of Corrosion X...

Edit: Whoops. I thought this was from a week ago.
