So, I wired up my AEs to the city light pins on my LCM (pin 44) over the weekend. Previously they were tapped to a wire in the ECU (a red/yellow striped wire) but i did not like tapping into the ECU. I followed some of the wiring details etc from derbo's thread here:

Some background before I get to the actual issues.
- I have Khoalty AEs and they have 2 "trigger wires" - one which connects to the footwell lights and powers up the AEs directly. This enables the fade in/out when you unlock/lock the car. The other trigger wire connects to the afore-mentioned red/yellow striped wire in the ECU. This trigger wire powers a relay, which in turn powers the AEs directly through the 12V battery terminals in the engine bay. Its this latter wire which I hooked up to pin 44 of the LCM.
- I coded the following to enable the pin 44 and it seems to light up the AEs:
SL_VO_ANSTEURUNG -> aktiv
PWM_ANSTEUERUNG_SL_VO_RE -> wert_01
PWM_ANSTEUERUNG_SL_VO_LE -> wert_01
Previously, I had also coded:
FL_DRL_MIT_RL = aktiv [tail light DRL]
PO_ALS_DRL = aktiv [city lights DRL - pre-req for tail light DRL]
Other LCM coding that I have in place:
1. Halogen high-beams with bi-xenon (PWM_WERT2_FL_BIXENON = wert_01)
2. Fog lights allowed with high-beam (FL_UND_NSW_NICHT_GLEICHZ = nicht_aktiv)
3. Front halogen DRL delete (GED_FL_ALS_DRL = nich_aktiv)
4. Front parking lights disabled when low-beam is on (SIDEMARKER_US = nicht_aktiv)
5. Triple blink - with 5 blinks via NCS Dummy daten modification
6. Euro hazards (BLINKIMPULS_WARNBLK = wert_04)
Now when when the key is in position 2 or the car is running, the AEs are turning on as desired. However, there are two issues:
1) When I hit the turn signal (right turn), this seems to make the AEs blink along with the turn signal. Ofcourse, does not happen when I hit the left turn signal since I am using pin 44 only (right city light pin)
2) The relay in the AE trigger wire is humming while the vehicle is running (not when the key is simply in position 2). Also, the AEs seem to flicker ever so slightly. I suspect that pin 44 outputs a PWM signal and not a flat 12V. I was hoping that this may be caused by the PWM_ANSTEUERUNG_SL_VO_RE being set to wert_01 so I set it back to wert_02 (default setting) but this completely disables pin 44 output and my AEs no longer turn on.
TLDR: How do I power up my AEs through a flat 12V output on LCM pin 44 without making it blink when I hit the turn signal?
I am hoping I am not the first one to wire up my AEs through the LCM and somebody out there knows the properly NCS coding to make it happen.
