Switch on the master cylinder in between the two steel brake line ports is a differential pressure switch.
ABS modulator should be approximately amidships, behind the water tank & between frame rails.
Brake switch should be located below the driver floor, you should be able to see it by looking up into the space ahead of the front tire and behind the steering gear. Should have a black rubber pad that the brake linkage pushes against when at rest, and releases when brake is pushed to connect the brake light circuit. It'll look like post# 2 in this link.

Yup--the wire on the very front of the MC [front of coach too] is the brake light switch on the 2003. Havent rigged a power source for the toad but would think a separate run to one of the many 12v power connections at the rear of the coach [oil stick/air filter compartment] would be a good source [use appropriate in-line fuse of course].

I ran a separate charge wire from my coach batteries with a fuse to the charge wire at the rear plug . I have a solar panel on my trailer so my trailer charges its own battery and the coach too and visa versa.

If you are looking for a brake-light-switched power source, I'd run a new relay off the rear brake lights.

Mike the linkage on my 2003 goes straight through the firewall then down at a right angle and into the master cyl. there is switch on the inside on the pedal but it activates the electric motor for the brakes does it also work for the brake lights that is the only switch I can find HEEEELP Robert
