What did you do TO your Bronco Sport today?

[Dude]

Looks good

did your vehicle have two connectors and the one ECU electronic box in the OEM position at the drivers side front fender area (left front fender)?

I recall a large connector sort of facing the front of the vehicle and just behind that connector was the ECU electronic box with its connector. Is that how the factory installed it?

if so did you move both connectors and the ECU electronic box into the engine compartment?

and did you have issues with the existing wiring length that prevented moving both connectors and the ECU? I’m assuming the length of the wires were enough to allow you to mount where you did in the engine compartment?

yes correct one box two connectors

it was in left front fender

yes i did

Small issue, I have to loosen some clips that hold the wiring, unplug the cable and move around then plug together,

the big cable goes on the left side and up
Smaller cable go under the headlight and up

That is great there was enough cable length allowing you to reposition the ECU electronic box up and into the engine compartment so that the box and its 2 connectors are much safer from being submerged in water. Other owners implied the cable length was insufficient which is incorrect.

now for some not so good comments. Sorry but I was an automative engineer with GM and designed various electronic boxes so have familiarity with typical automotive connectors, ECUs and other electronic boxes as well as the environmentals..,

The engine compartment is an extreme environment, two extremes are

Heat (likely is much hotter in the engine compartment than where the OEM box was mounted around the left side front fender).

Vibration: the OEM location for the ECU positioned the ECU vertically, in your pic the ECU is mounted horizontally, and it’s not clear how securely the mounting is now relative to the left side front vendor mount. Horizontal mount will have different characteristics than vertical mount.

There are a few other potential issues as well.


Not saying at all that you will or will not have issues with the ECU relocation and you may never hit extremes that others might .. say in a desert environment where ground temp exceeds 120°F+ or in extreme cold or under high vibration conditions like off roading.

On the good side, the ECU and its 2 connectors are now far better protected from submersion.

Engine heat yes well i hope it will not happen good that’s you notice that

i can always put some air to it , put some extra air hose to it im gonna do that ,

Its not so hot here in Iceland but hot engines and hot electric box is not good blend ?

Iceland?? Ok never mind lol

how about the horizontal mount vibration?

 

[Rhel]

i can buy stabilitzer under the bracket , something that they are using for cameras then she’s always like floating

I don’t know if it’s matter she is in like 20 degrees up

Seems unlikely in Iceland you would have heat issues on that ECU in the engine compartment. My comment was for those following your footsteps who live in warm to excessively hot climates. ?

Vibration of electrical components is a design concern but I would have no way to know for sure your mounting is any worse and could actually be better.

Ford would have tested along with the 450,000+ Bronco Sport owners where the ECU is mounted in the OEM position in the left front fender area.

For those interested, here are a couple of other links related to moving the electronic box mounted in left front fender but Rhel’s mod brings that box all the way up into the engine compartment.

Yeah it’s worst place ever for electricity box water , mud , snow, bumpy roads , off road, river crossing, flooding roads,

why there ?

 

[Roadeo Girl]

Just for information I have Goodyear wrangler workhorse 235/70/17 they are 30 inches exactly , they fit with about a 1/4 inch of space front of wheel and back of wheel on the front tires , I don’t think you will fit the 255/75/17 they are 31.1 inch .

What fender flare do you have?

 

[Rhel]

Let us know how it turns out .

255/75 R17 32,8” they fit if you take the inner flear off, im not gonna do that ?

so 245/75 R17 is 31,7” they’re will fitted also 255/70 R17 is 31” they will also fit

 

[Hitman11]

Made the weird side trim functional

Here is what I have on my flares.

see here i did have Volvo XC 90 today in oil change . Volvo did put the box in same position
