Maybe I am on to something......   I read that SYNC 1 & 2 use the FAT32 filing system on USB, whereas SYNC 3 & 4 use exFAT..............   Would that make a difference in the way files formatted in FAT32 are organized and read by the SYNC 3 & 4 systems??

Hello. Can you tell me how I can register? I keep getting the following error:   You are not allowed to use that email address on this site.

Thought this 58 second video about grill shutters was interesting and may be helpful to others, like me, who had no idea my vehicle had such a thing.         

You do not need to remove the BCM or solder anything. Instead, to add a wire, you unplug the connector from the BCM, then you can take apart the connector, and push a new pin into it. You can access the BCM by reaching up under the dash, and you can remove the small cover in the front that is right below the headlamp switch.   Program with FORScan. Changes in BCM to enable rear fog lights. And IPC to enable the indicator.

Boost PSI can be set with a tune   I don't know why you want to shut off / completely remove the grill shutters.  There are there to help your engine warm up.  More critical in Minn - E - Sota than in Arizona.   If you are thinking of installing a larger front intercooler, you can trim the shutters so it will fit.  Directions can be found elsewhere in these forums and on Youtube

Hey Wubster,  Were you able to find the changes you made with forscan to enable the menus on screen?

Story continues: analyzing wiring schematics from @Haz and comparing with Service Manual i have - built based on my Edge ST VIN.  Steps to be followed as per my understanding: 1. Install light switch module ( HEADLAMP SWITCH) with one that has rear fog switch button. Already done. 2. check if wire (CLF57) connecting HEADLAMP SWITCH module, pin 2 (REAR FOG) is in place and go to BCM pin 8 (REAR FOG).       What if there is no wire? To run a wire is not a problem from HEADLAMP SWITCH side. But how about BCM side? My VIN based Service Manual says BCM C2280G connector pin 8 is "not used". If there is no metal contact there then what? If it is only about putting metal pins in the connector (harness side) and crimp a wire then the question is - where to get suitable pin from? If BCM side pin is missing then... Don't tell me i have to take the whole BCM out of the car, open it and solder/whatever new connection inside:) Then another question to you guys - how the heck to take it out? Or even how to have some access to BCM? I saw BCM during installation of HEADLAMP SWITCH - it is so deep under the dash and there is zero room for hands not mentioning any manipulation around connectors!  3. Check if there is wire (SBB67) going from BATTERY JUNCTION BOX connector C1035A, pin 6, to BCM connector C2280B, pin 21:   By looking at the wiring schematic it looks like this wire (SBB67) is specific for REAR FOG lamps - is it truth? But then 50 Amps fuse?! Or maybe this schematic is simplified and inside BCM this wire powers more things? At least I'm bit positive here and my VIN based Service Manual shows C2280B bin is occupied:   4. Check is there is, if not, run new wire from BCM connector C2280F, pin 25, all the way to the back of the car to connector C438 (if exist...) and to DIY lamps - do it yourself as i haven't found OEM lamps that fit in place of original reflectors in my bumper (USA ST, 2022):( Then the other wire (negative) to some ground point in the back. And here again, my VIN based Service Manual shows BCM connector C2280F, pin 25 is not used:     ...so the same question on how to install it:/   5. Adapting the whole system to make it work - will it work straight away after the connections are made or some adaptation/programming is necessary? ForScan - how, what modules, etc - but for the moment i need to win points 1-4...   When i get back home i'll try to find some time and do detailed checks and make how-to story for anyone interested to follow the same path.   Please put some light on the topics highlighted above. Those missing wires and empty slots in BCM worries me the most. Thanks!
