I apologize if this has been covered I’ve had my truck for a while and I am just now getting to this.

I have a 2006 Dodge Ram 1500 night runner edition ( equivalent to the sport I assume ) anyways I wanna put a brake controller in it but have some questions.

i installed the receiver hitch and the 7 way light plug. The 4 wire plug had a connection so I just plugged it in with no problems. However I have looked under the dash and found the blue connector for the brake controller and no problems there. But I have looked all around the rear of my truck and have not found the blue brake controller wire. I’ve read a few forums but their wording is very confusing to me. I do know I need the constant power which is no big deal I can run it from the battery but how do I get my controller wire ran

thanks guys.

 

Welcome to DF! Moving this to Third Gen Ram section for ya.

 

Hopefully someone can provide update for you. My experience is that wiring for accessories like trailer plugs and cab lights is not consistent.
I rec starting at your four prong plug and trace the wiring forward. You'll need to open the loom cover, and may need to cut back some electrical tape. I suspect the blue wire will be in the bundle between the trailer plug and the cab.
You may also want to locate the red wire for aux 12v and I believe green wire for reverse lights.
