Late model XCM chassis, brake monitor light.
I recently upgraded from a 2017 Fleetwood Discovery 40E to a 2020 44H. I'm trying to hook up my own toad brake monitor light. Thus I'm trying to locate the wire that is connected from the rear of the coach to the front. The Invisibrake on my toad utilizes one of the wires in the pigtail to signal the coach that the brakes are on. I need to locate that wire inside the coach. I expected to find it near the steering column but haven't found it. Any help appreciated, else I'll contact Freightliner on Monday.
