brake light and oil pressure switch.S1 4.2

Hi again . In the pile of bits is a switch and I don't know what it is . Either brake light or oil pressure switch .They both look the same to me . I am using an oil gauge that uses a capillary tube and a 15lb oil switch warning light. Thanks Bryan

The brake switch will be open circuit between two twrminals. The oil pressure switch will have just one terminal and have some measurable resistance between the one terminal and the body of the sender....

Thanks Cactusman . Can someone tell me how the tailgate bracket attaches at the bottom. This is a fixed head and it has had a lot of bodywork done on it and there does not seem to be any holes just inside the boot near the back panel. Thanks again Bryan.
At least its giving me something to do in these uncertain times.
