Question:
is the 751220 switch the only way I can hook up the 9400 to my truck? Will a brake relay work or not? I dont have access to a switch and need it in a week. Thank you

The RoadMaster Stop Light Switch Kit, # RM-751220, that you have referenced for GM trucks and SUVs that have adjustable pedals is required in order for the Roadmaster Even Brake Portable Proportional Braking System, # RM-9400, to work.
