Check Chang 1 Post mentioned earlier in this thread ...... you can get rid of the nuisance horn operation on the CCS by removing wire on the clock connector from memory .. mine did this until wire removed ! .... You don't want that every time you set the CCS.
I think brown/yellow pin 11 and insulate ... and others as 26-31 .... ' How to Retrofit MFSW and Cruise Control ........................................................' print out items 1-6 snd use as check list of FULL install .. it will stop you missing something.
