Hi Bigwinn.
Pics aren't the best but this is what my car looks like. Something is missing from behind the rear view mirror.

If I had to guess it's possibly part number 4 from the diagram but if you can make out from the pics I have exposed wires (yes cobwebs too car has sat on drive for 2 years due to EPS failure but I am now getting everything back to working order on it).
I would really appreciate it if you could hook me up I think a garage took them off then never bothered putting them back on again this was 4 years ago so long gone.
