OLD vs NEW ASC Switch wiring.

[Southernboy]

Anyone doing a console change and fitting the newer switches with the round buttons will come to the ASC switch. The old switch has a different connector and in the back of the switch you will see 6 pins in 2 banks of 3. The new round button switch has only 4 pins in a line at back of the switch, and therefore the "old" connector will not fit. First off you'll have to find a suitable connector with 4 in a row female ports. Next, the switch pins on the new switch are numbered 1 - 4.
FYI.
P.1.......Power (from Fuse 21) Green Blue Yellow wire.
P.2.......Earth. Brown wire.
P.3.......Dimmer light power. Grey Red wire.
P.4.......Contact to ABS/ASC Module. Blue Violet wire.

That will sort out the re-connection in the correct positions for the new switch.

The 4 pin connector is available from and can be ordered online at:- http://www.mouser.com/catalog/catalogUSD/641/1387.pdf
4 pin connector part #......571-1022412 ($.1.33) - You need 1 off.
4 x locking connectors to fit on the ends of the 4 wires...Part # 571-876673 - You will need 4 off ($0.31ea)

BMW do not supply these items, and consider them to be part of the wiring harness.

Mouser electronics carry a huge range of stuff, and may be of interest to others who are interested in such stuff...

Perfect, will be hitting this hurdle soon with my own console change...Your info should make things a lot easier once I get all of the bits together.
