to MPDC2056, Thanks for the pictures you posted on this forum, I've seen 4 to 5 other people looking for wiring info for adding fog lights to their SPORT model. I just added an OEM set of fog lights on my 2015 Renegade Sport and am in the process of ordering the OEM in dash switch. Do you have any additional info on the wiring process such as the diagram you mentioned the dealer technician gave you. Did the final jumper wire and flashing to the BCM complete the fix? Did the tech have to run a new wire from the switch connector back to the fuse box or BCM OR did your existing wire harness from the dash switch work and he just needed to do make a short jumper from the fuse box to the BCM? Also, did the interior light fade controls on the right hand side of the switch work after the Dealer Tech did the work? These are some of the questions from other forum members I've read. SCAN

Hello from Austria

my father has a sport renegade and a friend from work managed to make the fog lights work.
i don't know how it is in the usa or somewhere else but here in austria the renegades do all have the same main cables only in the bcm the functions are locked and as we here know from FCA it's not possible to make them work like on the higher editions.
but back to the main point. i don't know if it's able to use them with the light switch that has the buttons for front and back fog lights. so my friend installed an universal switch thats next to the usb hub, the cable that goes into the bcm he cut off and made it stand alone, the control circuit comes from the head lights, with the limiting light it's not working cause that causes troubles with the day light. if you wan't the fog lights go work with the limiting light you need to lay cables from the back lights.
the turning light function is not available.

i hope you understand me and sorry for my bad english.
long time ago for me that i need to use it ^^

Still blown away that no resolve has been posted regarding the final status of OEM Fog Light Install. Mine are all in, flash took, but still do not work. Obviously there is something not connected on the Sport Model to allow them to work, and nobody has posted a fix yet. I have friends that work in automotive, and are puzzled. Local light place want $200 just to diagnose the wiring, or over that to rewire it. My last little car had no issues installing and flashing oem fog lights, and bumbed Fiat/Jeep has made this a little more difficult. Not giving up yet though, because my wife has the Latitude, and ready to do a side by side look at things now. Hope for resolve.

Add me to the list Looking for a Resolve

Same as others... 2015 Sport model..... I added OEM fogs....Changed the switch and took it to the local dealer to flash, which they did. The tech at the dealer read my notes about the wire harness from the fogs terminating in the fuse box and exiting to the BCM. He even looked at the wire connectors on a Latitude and the were the same. Because of warranty, they said they were not allowed to do any custom wiring. They saw my notes about "The last Step is to find the wires. These need to be connected to the relay and everything should work.....The relay is one of the 20 amp red ones in the fuse box." The dealer techs (2 of them) searched for a work around since they could not run a jumper to the relay as per notes. They even talked about replacing the entire BCM and reprogramming. After 3 hours searching for a work around they threw in the towel. I was only charged for the computer flash. I'll take my Sport Renegade over to a local customizing shop and see if they can finish the last step of connecting the fogs to the relay. Just thought I would check this forum to see if anybody was successful wiring the fogs after the BCM was flashed and if so, what was this final process.....

Wiring steps needed to power fogs on a Sport Model

:nerd:MPDC2056 I think"Mike" …. I ran a similarthread (Under SCAN) on installing OEM Fog Lights to my Sport Model. Fog Lights, Switch & Flash are complete. I'm just searching to find someone who has completed the final step of getting the power from the battery to the fog lights. Do you have the wiring steps and do your OEM fogs now work off the replaced switch? There are three other members just in the past month on my thread also looking for any instructions on running the jumper wires to send power to the OEM fogs for their Sport models and several on this thread. Any help is appreciated.

My basic understanding of how a fuse box is wired is that if power is not already run to a particular fuse/relay, then you would need to jump the power from a fuse/relay that has power in the correct "state" of the key. This means they may always have power supplied or only when the ignition is on. This is just for the power.

As for the BCM portion, the first thing someone needs to do is compare the plug on the light switch from Renegade with no fog lights to one with factory fog lights. It's possible that there is a wire or 2 missing on the Sport models. This would mean the BCM is not getting the signal to turn the fog lights on. If the wiring at the switch is identical, next would need research into whether there are more than one part numbers for the BCM. It may be possible that the BCM in a Sport physically has no controller for the factory fog lights and a Latitude BCM would be needed.

One poster above said they are able to cut the wire running from the fogs to the BCM and splice it straight to a switch which worked. This leads me to believe that the limitation is either the BCM itself, a wire missing from the light switch harness to the BCM and/or needing to energize the fuse/relay for the fogs.

It would help to know if someone would confirm if the auto lights started working after the re-flash. If they did start working, that signals that all necessary wires are likely running between the switch and BCM and would narrow down the issue to the BCM itself and/or the need to jump power from an energized relay/fuse to the fog light relay/fuse. This could be easily confirmed by using a short piece of wire and running directly from the battery to the fog light relay/fuse.

Hello guys. I know I don't have a jeep renegae but I have the new compass 2017. I follow up this diretions into buying all the related parts installing them and going to the dealer... only to find out they could not activate fog lights.... Well months later in other forum people where talking about AlfaOBD and how it can make wonders and miracles on different dodge vehicles and to my surprise my jeep compass was supported. (renegade is also supported). In my surprise you with the app can enabe thte fog light. the BCM has all what it needs. its really on the software side that they must be activated. just letting you guys know..

I had to deactivate my fog lights but that's other topic.


I can add pics later..

Update.

Done
Brought the correct fiat cables. In my case the grey OBD cable. And did the proxy and everything works accordingly. And my sport compass has factory OEM with switch fog lights.

Beware. Each time you go to the dealership. They reset the computer and I have to turn on those options manually and do a proxy alignment.


In theory.
No fuse box cable jumper wire needed.
You just need to flash the bcm.

So if I purchase the AlfaOBD Program, the OBDLink MX, and an Alfa Fiat Adapter 6 Grey OBD Lead cable I will be able to activate the OEM Fog Lights I has installed, and even be able to turn on the AUTO Light Switch I put in too? I could only find the Gray cable in the UK, but this should work on my US Jeep right? Thank you for all your help people.

AlfaOBD?

So if I purchase the AlfaOBD Program, the OBDLink MX, and an Alfa Fiat Adapter 6 Grey OBD Lead cable...
I'm looking at this, too.
I already have OBDLink SX.
If I understood AlfaOBD's website correctly, (unlikely) I would need the gray (and yellow, I think) cable, along with AlfaOBD software.
IF I understood it, OBDLink MX (the bluetooth version) does NOT need additional cables.


If someone who has and has used AlfaOBD could pop in with info, that would be great.

Zombie has the right suggestion...wire it to the dims by the front fender.... and it works. Ran a line from the battery to a relay. The relay is powered by a line to the dim light in the front driver fender. The power from the battery goes thru the relay and out to the fogs. The dims and the fogs come on in the first switch position... the headlight add in in the second position. I live in Florida where we get a lot of fog in the mornings and this set up is good for me. At night, both head lights and fogs are perfect for night vision to avoid gators on the road. HERE'S THE LONGER VERSION (I did the original changing of the switch and after a flash at the dealer the fogs and auto light position would not work.) The dealer service techs were clueless on these Fiat systems (I left the changed switch in although you can use the original switch without the fog push button). I also tried going the AflaOBD route but never got that going either. I have an OBDLink MX, and the grey connector but my Android would not support the AlfaOBD App. I even bought the software online directly from AlfaOBD for my laptop but was told by them to purchase it directly thru the Google Play store for updates. AlfaOBD sent me a refund but I was blocked getting the software thru my Android. I'll use the OBDLink for other vehicles. One last note:: Seems to me that it is possible to wire the light switch fog button directly to the relay and bypass the BCM. You would need to test which wire in the light switch harness connects to the fog button and then cut & run that wire to the relay instead of the wire spliced to the dim. So if you want Fogs the simple way... the Zombie way.... Connect to the dims. Want an even simpler way, take it to a radio shop that has the relays in stock and have them wire it.
