Trailer Tow Prep Wiring

A pre wired kit should mean some sort of harness should already be installed in the rear underside, but this is often not the case. Odds are you will probably still have to run wires to battery, brake controller etc.

It might be something the dealer had to install during the pre-delivery inspection (PDI), I suggest you start by following up with them first, speak to your sales rep.

Thanks I try the dealer again.

missing module

I brought mine in because the dealership promised me that they would look into the issue for free. The conclusion is that FORD chose not to install the module that controls the wiring. They estimated the Module price at $154 plus installation fees. I am choosing not to go that route. FORD will not cover the cost of the Module. I'm requesting part numbers when I pick up the car tonight and I can post them on here if that would be helpful to others. I do appreciate that the dealership is not charging me the diagnostic charge being they had no idea what the problem would be.

Same Question

I recently purchased 2018 Ecosport SES. The window sticker states "TRAILER TOW PREP WIRING". Noone at the dealership where I purchased seems to know what this means. I just installed a trailer hitch, and would now like to add the trailer wiring/connector. Does anyone know the part# for the electrical harness/connector? Do I just need a wiring harness? Or are there other controller, fuses, etc components needed?

I ordered one from ford last week , just received it , but no instructions, I know it came with a module, and a wire that goes to the battery, just not sure about concealing the wires or how to install the kit

If the harness is a separate item i bet that down the road it will be something we can buy aftermarket for 1/3rd of what the dealer charges. Something to keep in mind!

ohiogary - can you post the Ford part# for the module you ordered? And price? Thanks!

I purchased the wiring harness from my Ford dealership here in Fresno, CA and it was $80. I was told they would install it for $150 and scheduled the service. Today, my day of installation was told it was a 1/2 day project and price was $500. The service writer and manager knew nothing about a trailer tow prep wiring even though it was on my window sticker as being equipped on my model.

for all those interested, Iam having my dealer install the parts to complete the trailer package. when this is finished I will be happy to share the knowledge. what i know so far parts and installation will be 400.00 and it requires a computer reflash. parts are ordered dealer will install when they arrive, my dealer has already done 2 eco sports b4 mine.

$400 trailer wiring from Ford dealer

Wow - $400 for the trailer wiring at the dealer? And the EcoSport supposedly comes "pre-wired" for a trailer...
As nice as it is to stick with a Ford OEM solution for the trailer harness wiring, I'm tempted to just
go with a solution from U-Haul. They will run the wiring (under the car, from the battery) and
connect everything and provide a trailer connector (with diagnostic LED) and include a 2-year "no matter what"
warranty. All for about $135.

I just had U-Haul install my hitch today, and they refused to do the wiring for it even though I scheduled(and paid in advance) for it online. I'm furious. I will have to buy a kit and install myself I guess.

The trailer prep that Ford says we get on our window sticker is not available in the US. They have them for Ecosports sold overseas. The wiring is there but no module is available here. I bought a trailer light converter off Amazon for $20 and wired it in myself. The prep wiring is under the drivers side rear seat. There is a hot wire there that goes to the Trailer Prep fuse in the under hood fuse block. The wires are there that go to the trailer plug behind the drivers rear wheel (Left Right and Tail, no ground) I ran wires that I scotch loc'd to the left turn, right turn, brake, and tail hot wires at the rear lights. Then you just have to find a ground. Works perfect.

I ordered a 4 flat wiring plug from Ebay (for vehicle side) and cut the plug off behind the drivers side rear wheel. I used heat shrink butt connectors to connect the wires together. Colors match there.

Total cost under $50

On my 2018 Eco the LH (drivers side) turn is Grey/orange, brake white/green, tail violet /green and the RH side is turn Green/orange, brake grey/violet, tail white/orange

At the rear light housings.

Can you post which converter you bought on Amazon? I'm about to make the purchase since they didn't do my wiring.

trailer wiring instructions

hawkjr9 - how about you detail out your solution for doing the trailer wiring. Include some photos, detailed step-by-step instructions, and a parts list, etc. Then post on here the availability of the instructions (as a download file) and ask for a reasonable "donation". I will gladly pay $50 for a instructions that I can easily follow, and for a solution that costs <$50 in parts.

Please consider this. It would be a public service!

well my trailer wiring is now working, installed by the dealer under warranty. FT1Z-15A416-A is the part number needed. the module shown in the parts list 19E809 for the ecosport will not work on american models. Ocala Ford here in Fl. can do it or your dealer can contact them

well not quite a 100 percent, have a hyper flash problem with the dash indicator lights , so don't know whats going on and neither does the dealer
