I'll check thereIn my 8100 international, the brake switch is on the back wall of the cab, kinda behind the drivers seat down by the floor.
Hi funwithfuel.Forward side of bulkhead. 2 spade switch in a push lock fitting Td into an airline.
4900Firewall. Between you and engine compartment.
What model truck, 47/4900 ?
No SirSo, did ya find it?
Its got to be in the air line somewhere after the treadle. Follow the wires from the brake lights back toward the cab, and follow the air after it leaves the pedal. Somewhere they meet.
Interior pic shows where my switch is in a 8300. Behind the upholstery.
Firewall pic, that's supply to the pedal, and the lines out to the brakes. Find which set is going to the brakes and follow them.

Yes, i actually purchased one from internationalWill generally look like a automotive oil pressure switch, larger diameter tin with a black plastic contact retainer center crimped in place, two wire connectors. Between the seats is most likely.
