The Roadmaster InvisiBrake Supplemental Braking System # RM-8700 can be spliced into trailer lighting harness before the diodes. Before meaning the wiring between the 4-pole connector and the diode. After being the wiring between the diode and the tail light. In the attached installation video (24 min. mark) Shane splices into excess wiring bundled up in the engine bay.
