Does this include the CHMSL ( Center High Mount Stop Lamp ) ?
The turn signals work fine when you say all other lights work ?

If so could be 2 things.
1. The BPP ( Brake Pedal Position ) Switch
1.1. The BPP has 4 wires on it
1.1.1. Tan w/ Red stripe & Pink w/ Light Green stripe are the shift interlock
1.1.2. Light Green w/ red stripe & Light Green wires are the Brake lamp part of the BPP.


When you have the brake off, the Light Green w/ Red stripe wire should have power on it ( from fuse #2 ) and when you press on the brake pedal, the Light green wire should also have power.
- If only the Light green w/ red stripe wire has power with the brake on and off, and the Light green wire never has power, the BPP switch needs to be replaced.
- If the Light Green wire does not have power ( and you are use of the ground you are testing with ) fuse #2 is blown.

- The fuse for the brake lamps ( Fuse #2 in the cab fuse panel ).
-- This is if the CHMSL is also not functioning

This should be what you need

So its a wagon? or I dont know what S/W is. If the license plate light works, the light failure sensor could be bad. It should be in the left rear corner area and have 4 wires. Green, Light Green, Yelow/Green and White/black. You should have power on the Green going into the box, and the Light Green out to the tail lights. If you have power on the Green, but no power on the Light Green, then the box is bad, either replace the box, or you can just connect the Green to the Light Green wire to get tail lights operating.

trick of trade... take a 9 volt battery and touch the wires to it.. the speaker will pop and you will know which one is which... do one color at a time
