All the time it shows rear turn light out (All works good but it blinking fast on dash)
Ps. Sorry for my grammatical, but i hope you understand
Are you using LEDs for the new separate turn signal bulbs? Are your tail light housings the factory LED lights?

im using reverse light as turn (changeing pins in bcm), then have to use resistors as reverse light.
stop is in normal place (tail light housings the factory led)

I’m not sure this will work, but you can try disabling the fault sense wire for the rear tail lights. I’m just not sure if it’s tied to the new dedicated turn signal circuits that you added to the BCM. I’m not familiar with the auto enginuity layout, but if it can enable the rear turn signals, it should be able to do this: Go to CBC I/O Usage and find “left rear door ajar switch usage” and disable it (or set it to none). Do the same for “right sliding door switch usage”.

Maybe someone know, is possible to change wires in bcm to use oryginal rear turn signal controll to my turn bulb ?
I saw that plug F pin 36 is left rear turn signal control, and
Plug E pin 22 is right rear turn signal control but i dont exactly know how to use this pins to control my bulbs 😕
Hope you understand

Yes. This is exactly what you need to do. I misunderstood you and thought you had already done this. Those wires SHOULD be there at the BCM already. I’m just not sure where in the body harness they end, since they’re not normally used unless someone is trying to do what you are doing. You need to find them and hook them up to your amber turn signal bulbs you are planning on using. Then you need to enable the rear turn lamps output in CBC configurable inputs and outputs. You also need to disable combined rear lighting in CBC features.

Ok, but ive found other pin look like rear turn signal.. plug f pin 42 look like rear right turn signal, plug e pin 3 look like left rear turn signal.
Plug e and f got rear left and right turn signal control and rear left and right lamp lighting fault sense maybe you know how to corrently connector this all ?

Ps. I enable rear turn output and combinated rear light not set. On oem rear turn/stop light is now just stop

I didn’t look at the connector sheet and spoke too soon. These are the two that need to be used. The turn signal drivers, not controls. So, C5/E connector pin 3, and C6/F connector pin 42. I think you might actually have to add those wires to the connectors. Since you have the settings correct, everything should work once you hook these up.

I add those wires + change led rear turn to „not set” and still „rear left and rear light out” 😕
Maybe have to do sth with control wire in lamp ? I use reverse bulbs as turn .

The rear turn control wires are only for the 7-pin trailer connector’s turn signals.

What happens if you change led rear turn back to “set”?

Ok. Make sure you are back to combined rear lighting disabled, rear turn output set, and leave led rear turns set. We need to try to disable the fault sense wires that go to each tail light housing. There should be two settings in CBC I/O Usage related to “rear door ajar” or “sliding door ajar”. These are what are actually used for the rear fault sense wires on our Ram trucks. I know you said you didn’t see them, but double check. They would be in the same section as “hood ajar switch USAGE (not INPUT)”.
If you don’t have those settings, you could disable the rear lighting DTC setting under CBC features. If you do this, you won’t get an alert if any of your rear bulbs are actually out.

Then, there’s a last resort of adding resistors to the rear turn signal driver wires, but, I’m sure you want to avoid doing this.
