Thank you
Takkey !
I finally got what i was looking for! I kept the settings I had for turning the fog lights on with the angel eyes:
MAPPING_NEBELSCHW_L_FUNCTION = 04
MAPPING_NEBELSCHW_R_FUNCTION = 04
And added the following to turn the fog lights on with the low beams:
MAPPING_SIDEMARKER_L_FUNCTION = 03 (Low Beam)
MAPPING_SIDEMARKER_L_OUTPUT = 0B (Fog Lamp L)
MAPPING_SIDEMARKER_L_PWM_LEVEL_STANDARD = 89 (13.7V)
MAPPING_SIDEMARKER_L_FIXED_PWM = 00 (pwm)
MAPPING_SIDEMARKER_L_PRIORITY = 03 (bottom priority)
MAPPING_SIDEMARKER_R_FUNCTION = 03 (Low Beam)
MAPPING_SIDEMARKER_R_OUTPUT = 0C (Fog Lamp R)
MAPPING_SIDEMARKER_R_PWM_LEVEL_STANDARD = 89 (13.7V)
MAPPING_SIDEMARKER_R_FIXED_PWM = 00 (pwm)
MAPPING_SIDEMARKER_R_PRIORITY = 03 (bottom priority)
Finally got what I was looking for - the fog lights are on all the time whether the low beams are on or off. I can't easily turn them off, but thats fine, i went through all this trouble specifically to have them on all the time.
