Generally
A complete cab button except chrome frame. It fits perfectly without any modification whatsoever. Please note that if the old contact is burnt out, and the reason is that it is getting a high load due to the electrical system of the cab motor being in poor condition, the new cab button will be overloaded and fail. The solution to the problem is to mount a double relay at the cab pump, then you only control the relay with the cab button, which then lasts forever.
