Rear Brake Lights and Indicator wires

[adamburgess]

I was wondering where the wire for the rear brake lights and indicators, are there any wires in the actual cab? could someone point them out to me as im trying to tap into them.

Indicators do have a presence in the instrument cluster, a multimeter will help there.

Brakes have a switch (possibly two, if you have cruise control) on the pedal.
