Brake Light Switch, Find, Remove, and Install Instructions
This is a two page doc outlining where to find the brake light switch, how to remove it, and then install the new one.

Note, do not move the brake pedal when removing or installing the switch. Let the brake pedal hang where it wants to. The switch design is actually cunning, and as such is supposed to make the removal and install fool proof. Hence if you think too much about it, you can wreck the new switch.

If you want to inspect the interior of the switch, wait until you have removed the old switch. You can then just unsnap the blue from the white to get it apart. Inside, the switch is quite simple, (no circuit boards), but it will probably show black dust from failing contacts.

I think the reason the switch fails is that the Normally Open, (NO), contacts of the brake light contacts were made too light to carry the current load for make and break of the tail light filaments. I also think the black dust created then fouls the Normally Closed, (NC), second set of contacts for the ABS circuit. As such, the Normally Closed contacts become intermittent in operation and display as a fluctuating open and closed circuit condition to the ABS system when the ABS should be seeing a steady closed circuit. Hopefully the replacement switch contacts are more robust and may be as I recently replaced my switch again just as a matter of maintenance. While in a redesign, ideally the NC contacts should be sealed or at least separated from the NO contacts, when I inspected the removed switch, this time there was no black dust present.

Probably the removed switch will have a Land Rover oval logo moulded into it, the new one, FOMOCO.
