Where is the factory connection for a trailer brake harness on a 2001 ford F250 SD?

Answer 1

you can buy the needed harness for this connection then all you do is plug it in --- The above answer is completely USELESS, i don't know who wasted their time writing it. I have the same truck and have been having problems with it, here is what I've learned from experimenting and talking to Ford service techs so far: The "factory connection" is located behind the license plate near the spare tire and attached to the bed body. It is an 8 Hole connector, gray in color, and a rounded rectangle in shape. Various Harnesses are sold that will plug into this however only one for 99-03(or 04) Super Duties will work. That being said, there are many adapters that can link from a RV type adapter, an electric trailer brake wiring adapter, or for just a 4 pin connecter. Another problem you may run into, is that some lights will be working and others will not, for example my right blinker and brake light work, however the left side does not and the running lights do not (for a 4 pin connector). This could be caused by a break in the wiring somewhere along the body of the truck (I checked mine this was not the case). This sent me to the local Ford dealer, where I found out that there is an electronic "module" that is devoted to trailer lighting and electronics that has malfunctioned on several Super Duties. It varies in price from about 250-500 and should be installed by a Ford Technician. BIG BUCKS thanks again Ford Jerks! On a more positive note, that I will be taking, You always have the option of splicing the actual tail lights of the truck and running a 4 pin connector from that (will not work for electric brakes, RVs, etc.). Research more information and buy a repair manual with a Wiring diagram before you do this! HOPE THAT HELPS BETTER THAN SOMEONES "NOT ANSWER"
