computer (idm?) in wheel well

[AUSPowerstroke]

hey guys, i have a 03 7.3l F250, im in the middle of plannin a trip away doing one of the biggest 4wdriving trips you can do here in australia, planing on goin early next year and am just trying to sort out some stuff now,

basically in my passanger front wheel well (lhf) there a computer which i think is the injector driver module or so ive been told, pretty much want to know 2 things as there is many river crossings that will be over bonnet depth when crossing

1. how common is it for the computer to fail after doing river crossing/mud runs

and if it is a comon thing that could be a risk this is my next question

2. can that computer (IDM) just be replaced or does it have to be replaced with the help of a dealerships computer, cause if its a big issue i might get a spare and take it with me,

i havent had any issues with water crossings and that computer yet and have done river crossing up to bonnet depth before, just trying to cover my base with anything i can see that might be a issue as we will be 1000km from a ford dealer and about 3000km from my home


cheers for the help

That IS your IDM, and it does Not have to be programmed, you could just carry a spare.

Maybe you could "grease-the-crap" out of the connector (thick silicone stuff) and get an advantage, it's fresh water -right? They are supposed to be waterproof and are routinely exposed to the water running off the windshield, through the cowling, in that corner.

If you expect to be submerging the electrical connections under the hood, although Ford uses excellent connections there, I'd be thinking of using that silicone grease on them all!
