Marker Lights

Sorry, for getting your hopes up. I was kind of excited until Jimmy pointed out the obvious.

Tap into wire or reroute to an upfitter switch an option?

I think Jimmy was talking about something like that in post #46 of this chain.

Whose looking for wire diagrams and which ones? I might be able to access.

Maybe make a thread for popular requests. This could be very helpful.

Yes Please! Try to extract any diagrams related to lights and ignition.

I tried to gain access to stelantis library y-day.. and the price was $1600 a month

It would be nice to get an offline copy
Another option - 3rd party firm with 3day access.

Tech authority service library is $45 for 3 days, $275 a month

I would try.
Is there also the option to have amber DRL? (I've seen everyone is considering Tazer for that, but I personally don't want to connect Tazer.)

Tazer is great. The amber lights can be set without "marrying" the Tazer, which is nice. Just plug and go. Unfortunately, Tazer hasn't cracked the RHO BCM.

This is going to be completely different than doing it on a TRX. The clearance lamps are not run off of a fused circuit in the fuse box like the TRX. F32 is irrelevant, that is a main battery power fuse for the BCM for its exterior lighting.
It’s hard to track this down on the schematics because the clearance lamps aren’t shown on any of the factory service manual schematics.

I did find what I believe to be the circuit for the clearance lamps though, in the connector sheets. Looks like the feed wire is the white/green wire in position 60 of the black C5 BCM connector (circled below).
You would pull that wire out, attach a fuse tap to it, and add it to fuse F54B on the interior fuse box.
I have no idea how the BCM would react to not having the load on that circuit anymore, so the better way to do this (if that ends up being the correct circuit) is to leave that wire intact in the bcm, and tap into it while using two diodes.

@Jimmy07 is correct, the key is to understand MODULE-BODY CONTROL

I got access to the diagrams..
Here the pins for C5 connector:

De-pin the white/green wire from position 60 of the black C5 BCM connector, then note behavior (did all the marker lights go out, and are there any errors in the instrument cluster).
If all is good, add-a-fuse that wire to fuse F54B.

The BCM is located on the side wall of the driver footwell, and connector C5 is circled below:

@Jimmy07 first part is done.
#60 is de-pinned. Inserted C5, turned the engine, turned on the parking lights: no marker lights, only headlights..
No errors as well..

 

[IvanNik]

The second step didn’t work, but I was in a rush.. will test tomorrow.

 

[Jdmdc5teg06]

I appreciate you trying this dude.. and with Jimmy’s help, I’m sure this will work and will be one hell of a wanted mod by most of us

With these diagrams is there a way to jump fuses to override the white DRLs with Amber? Sounds like the TRX's could do it without the Tazer. Or are we just at the mercy of Tazer release which is TBD?

I think the headlamps are controlled by CAN

I think #60 might be the wrong one, or at least not the only one.

This time I measured the voltage: F54B has 12V (with the ignition on)

So I connected the #60 wire to F54B and turned the ignition—nothing happened.
Then I turned on the parking lights—they worked.
When I disconnected #60 from F54B, the lights turned off.

Did you ever get this figured out?
