is there and where can i find a plug in for my electronic trailer brake controller for my 05 F150

 

any body that sells the controler will have the plug for them. NAPA orielys ford.. there cheap like 8-12 bucks

 

The factory wiring harness is under the dash near the steering column.

The specific controller adapters can be found here: http://www.etrailer.com/bc-2005_Ford_F-150.htm

 

how and where do you all mount the break controller?

 

A quick search should give you plenty of ideas from different folks. This topic has been posted and answered quite a few times.

 

Check this thread out, there are pictures of the two most common mounting areas.

By the way, can anyone tell me how/where they spliced into the blue wire when they added the 7 wired plug at the back of the truck? The wiring harness is snugged up tight against the truck body and I don't want to mess up more than I have to.
