The switch is located at the top of your brake pedal. You pretty much just have to unclip the old one and put the new one on. You need to make sure it is adjusted so the brake lights are only on when the pedal is pressed.

Here is a guide and some diagrams (below)

Electrical connector into switch.
Switch by snapping it onto pushrod.
Retainer onto brake pedal pin. Use 11mm (7/16 inch) socket to push new clip on pin.
Negative battery cable.
Enable SIR.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Would removing the lower half of the dash and remove the two bolts that support the steering column give me better access to the switch?

It might, if you do that be careful of the small cable for the shift indicator, if you pull too hard it will break the indicator

I removed the steering column. It opened up the area at the brake light switch a lot. It was not hard at all. It is better than laying on your back with your head in the dash for an hour fumbling with the switch. Once the column was removed, it was a snap. I have come to find out that these model of trucks with this type of switch may quit working the brake lights and the driver not know it! I did not know until my wife was following me one day. I do not know how long it had been out.
Thanks for your help. I will get to the feedback ASAP.

The park lock solenoid is actuated by the brake light switch. Are the brake lights coming on?
