this is a steering column mounted switch..  TWO PRONG 

For MANUAL FACTORY cars... 69- to 81 era

Most all RHD conversions..have NOT reconnected the linkages that allow this switch to work from the gearbox linkages up the the lower column.

If yours is RH Drive and manual..check what you have .. you MAY have a switch on the side of the gearbox set up using the linkage rods.. may not too..but may.
