Hello Everyone

I am going through the error codes on this S type line by line and fixing them and was hoping someone can tell me which pins/ wire colors lead from the steering wheel horn switch. I am pretty certain that the casssette needs to be replaced as I have cruise control issues and various error codes relating to the air bag and radio controls but I want to make certain the horn switch is working properly. I cant seem to find the wire colors in any of the schematics i have for the steering wheel / cassette mechanism.
The horn works with everything but the steering wheel
On a side note I have the CATS system working 100% error free and the car (2001 S Type 4.0) handles like a dream. Not only were the pins on the ADCM corroded but 2 of the wires to the plug had breaks as well. I opened the box up and the PC board had corrosion in a couple spots too. I was lucky enough to buy a used one for $35 from Ebay. With the new brakes and new tires on 20 inch rims I think it handles better than my 2013 Cadillac ATS Premium

Thank you for your help - This forum has saved me a lot of money from going to a dealer

 

Looks like Fig 19.1 (I searched the PDF for horn)

 

I have looked at fig 19.1 but I do not see where it tells me the actual color code of the wires ? I do have my car in my current signature

 

All over it!

Look earlier in the PDF where it's all explained e.g. under Wiring Color Codes
