I can’t seem to find where to plug in my break controller under the dash. I went to the deal got the pigtail to connect my controller but can’t find the plug. The only open ended plug I found is round and smaller. The one I bought is bigger and square. Am I looking at the right thing, I must be over looking it. Need Help, thanks in advance!

 

I have an 04 F250 and the plug for my controller is located to the left of the 4 wheel drive lever.
This image doesn't show the plug, but you can see the cable from the controller going up and behind the dash. It's the cable with the yellow tag touching the 4 wheel drive lever.
Hope this helps?

 

Keep digging, it's a little more towards the center. Not very easy to get to, but you've only gotta do it once...

 

thanks I will go look and see if I can find it, I had been looking more straight under the steering wheel
