Which Wire? Brake Light Wire Off Switch

[mickey53usa]

Looking for the brake light wire off the Air Brake Switch - 99 Winnebago Adventurer - Freightliner XC Chassis. Cannot seem to locate a wiring diagram of the brake switch - Photographs attached - Looking for the wire going to the brake lights that gets power only when pedal is depressed. need to tap the wire for my TOAD braking system.

Thanks

Well, called Freightliner - got a copy of the schematic - will try and paste it in. Two switches wired in parallel. Red power on one side, white wire going to the brake lights on the other. In case anyone needs it.

For the Unified brake system, the white wire was the wire you want, at least on my 2002 Freightliner. Be sure to check that this wire has power only when the brakes are applied.
