If i remember right you were asking about tacho before, and didnt have "W" plug on your alternator? Since, that makes things WAY harder.

BTW, i need the wiring too. I took off my instrument cluster two times, and resoldered all joints - nothing changed - tach is not working. Then I found some corroded and some cut cables on the alternator - it was charging, these were some other signals. I cannot see if there is some letters on the connectors without pulling it, which I cannot do right now.
I have two cables and one connector with two pins connected to the alternator - which one is which? My tacho is now working, but it is sluggish and have slow response, and it seems to me that it is not working correctly - it's hardly gets past 2.5K rpm.
Any suggestions?

The alternator could just be going bad.. Are you sure the belt isn't slipping?

Mine doesnt always come to show idling speed when releasing throttle and stopping, its like everytime different, between 800-1100,
when its set to 900. But when revving, it will in my opinion work properly.
I believe problem is on instrument cluster.

So, is there some schematic with explanation of the extra wires? I could not find nothing in VADIS, and I don't have a green book for D24T.
As I said, I have two cables + one connector with two wires, beside these that are actually for charging. What are these wires for, except for the one that is signal for the tachometer?
