Expert:  roybelding replied 1 month ago.

chassis module can be either under the hood left side inner fender or it could be mounted under the cab left side as well. I have also seen them mounted behind the cab on the frame. they put it wherever they want when they make them

but how do i know which plug to check for the brake light? can you give me further information please? how can i review the diagram
Expert:  roybelding replied 1 month ago.

you have the wire colors listed on the diagram. let me see if I can find something else

Customer: replied 1 month ago.
the problem that i have is that the red/white wires under the chassi are cut and theres a module thats bypassed, so i need a diagram for the brake system complete, from a to z
Expert:  roybelding replied 1 month ago.

you need to ohm out the wires for that. I can give you the origin of the wires but beyond that you need to ohm them out to the rear of the truck.

the brake light switch sends the signal to the module and then it goes out to the rear lights. the connector is shown in the first diagram I sent you.
