Wow....this pre-wiring thing is a joke and no one at Ford seems to know what's going on. I had one dealership order me a connector that goes to the pre-wiring on the back of the vehicle. I hooked it up only to find that there was no current. After spending 4 hours at the dealership yesterday, where they tried to figure it out....they tried to tell me it doesn't have the module that connects to the electrical system and it would be $500-$700 to have that installed. They really need to do a better job of explaining the factory "pre-wiring" to their salesmen so they can, in turn, explain it to the purchaser. I'm very disappointed in Ford. To me, "pre-wiring" is false advertising, as it would imply that everything's ready to go, you just need to plug and play. The lack of information out there is astounding and very frustrating.
I'll be installing my own wiring...for $75. Part No is FT1Z15A416A.
No one has t-connectors out there for the 2018 Ecosport so it will require splicing but I've done it before so I'm not too worried. Just frustrating that I bought a vehicle under the impression it would just be plug and play and it took this long to get an answer and it's basically that the "pre-wiring" is a joke.
Still love my EcoSport just disappointed with the lack of knowledge and false/incomplete information at purchase. I will be writing a letter to the dealership from which it was purchased as well as to Ford Motor Company.
