I have a 1994 2500 Diesel. Does anyone make a plug in brake controller wiring kit? Everything I have searched for only starts at 1995. I need to plug into the brake light switch for my brake controller. I really don;t want to make a splice if I can avoid it. Thanks

 

Since you have a 94, it may not be pre-wired for a brake controller. Here is a good reference that shows you how to do the wiring.
