Dear Sirs,

I am from Poland and just bought an imported Ram 1500 5.7 HEMI 2012yr. Well, I have to make some changes in exterior lighting due to our regulations. One thing is to install rear fog lamp. I found in the TIPM configuration menu this:
Configuration of #10(F12) output -rear fog lamp: enable.
I just cannot identify which pin is #10(F12) to connect my fog lamp to it.
The second question is if there should be a possibility to set bulb type to LED in the TIPM configuration menu as it is possible in 2013+ models? To tell the truth I can't find those settings for now and I am wondering if it is a problem of my OBD interface/hardware or my car doesn't give that possibility...
I will be very grateful for any answer.

Unfortunately, for the 2012 RAM 1500, the Totally Integrated Power Module (TIPM) does not have the ability to configure bulb types (like LED). I am not sure where you got the fog light info but all I see for pin TIPM configurations is "J" and "M" ? Here are the TIPM wiring diagrams so you can see what I am talking about. Check out the images (below). Let us know how it goes.

Thanks for the answer and the data. I couldn't find the pin on which the new rear fog signal was supposed to occur. I have installed new separate switch to operate the lamp. Anyways thank You very much for help!

Suggested Repair

The 2012 Ram 1500 TIPM cannot configure bulb type to LED. The rear fog output labeled #10 (F12) was not identified in the available TIPM pin configurations, which showed J and M; compare the TIPM wiring diagrams, and use a separate switch to operate the rear fog lamp if that output cannot be located.

Conversation Summary

The owner of an imported 2012 Ram 1500 5.7 HEMI asked which TIPM pin is output #10 (F12) for a rear fog lamp and whether the TIPM can set bulb type to LED as on 2013 and newer models. The expert said the 2012 TIPM cannot configure bulb types and did not confirm that fog-lamp pin, noting only J and M configurations and referring to TIPM wiring diagrams. The owner then installed a separate switch to operate the lamp.
