Hello to All !!
I have a 2009 Honda Fit (actually I live in France, so the car name here is Honda Jazz) and I've ordered a Rostra Cruise control kit that supposedly
fits to this car, I know this subject was already mentioned in this forum, but still I can't find the info I basically need.

My first problem is that I just cannot find any info / diagram related to the harnesses of wires under the fuses in the fuse box (see picture) and I just don't know what these
wires are precisely doing or info they provide. (I made a red circle on them) Does anybody has this diagram or info for me ? I would be thankful.

The (horrible) rostra instruction gives a picture of the wires but in my car, it just does not look at all like that. According to rostra's picture I should see this and find this red wire :

But in my car, the same area looks like this :

My Fuse Box1

I Just don't have that thick red wire anywhere... Does anyone have a clue here ?

Thanks For reading !!

 

Anyone having some diagrams for harnesses for a 2009 Honda Fit .?

 

I would offer my service manual but it's only good for the American second gen. There's so many variations of the second gen I wouldn't use it for reference. There's online subscription based wiring diagrams that would be region specific and more of a help to you.
