Hi all

Does anyone posess genuine C5 Mk.1 wiring diagrams please.

Most specifically for cruise control area. Ive got one here where the Redundant Brake switch doesnt change state. Ive tried a new genuine brake switch, its the combined 4 wire switch. Brake lights work, but the redundant doesnt , meaning cruise wont currently work.

Cheers

Hi Paul,

Not sure whether this info is of any help (James's, 9 Sep 2019). You have probably seen it already.

Here you go. Now there are 2 diagrams for this engine - one with, and one without the cruise control - so obviously I haven't put up the one without it. However, if you think it will help you compare the 2 systems, let me know an I'll put the one without cruise fitted at factory for comparison.

I notice in the wiki pages of fcf the list of numbers do not have item 2120 in the list. It goes from 2112 to 2200.. From the diagram I assume that 2120 is the 4 pole combined brake and redundant brake switch unit..

It is the brake light and CC-trip switch.
