Nightshade - Happy to report the above worked perfectly with one minor typo correction - it is BCM: 726-29-02 -> x1xx xxxx xxxx - so thank you again - the DRLs are a heck of a lot more effective now.
Thank you Nightshade - Duh. ...your hint caused me to dig deeper in other forums and I tripped across the following which I think you had a hand in - about to try these settings next:
DRL - Position Lamp Cfg
BCM 726-29-02 x1xx xxxx xxxx
position lamps at full brightness like Super Duty...
Folks - a little stumped here - tried both methods for brightening up the DRLs - BCM: 726-42-01 -> x2x2 - xxxx - xxxx ; and 726-38-01 ---> xxxx 5Axx xx. When saving it is telling me in effect that these are incompatable configuraiton changes. Hints and tips welcomed - mind you I have made plenty...
