Speed Sensor connection

[Officer305]

Hello,
I wonder if any of you could help me. I have a w203 MB C Class C270 CDI. I have fitted a in car pioneer system which also has SAT Nav. The unit is an Avic X1. I contacted Pioneer re attachment of the Speed Sensor wire for the unit. This was the reply.

For your year of Merc model 203:

3-way contra-connector (nr. 24 or 26) under fusebox in ECU-box position 3, if
equipped with a 3-way blue connector: position 3 black;
12 volt pulse,


Regards.
Customer Relations
PIONEER GB LIMITED

Unfortunetely there were unable to supply a Diagram.

I am looking for help to find this connection so I can connect the speed sensor. If any body can help I would be most obliged. As much direction as possible would be appreciated.

Thanks.

The speed pulse comes out of the BIXENON AUTOLEVELLING position which is plug 24 / socket 24 on the underside of the front fuse box. So naturally if there is factory fitted xenon then the cable is in place.

The remove fuse box place wipers in the noon position (big hand and little hand pointing to 12).

Remove key from car

Remove fuse box cover

Remove wiring that is visible by unclipping from sockets

Remove 3 screws

Observe.

The pins needed and the part number of the connector are probably in this archive and most certainly in MBWORLD.ORG under "463 COMAND"
