Sorry forgot to add that to list of things I have done.
Before I did the 7pin mod. I removed the CDL switch and put the factory terminator back on (little connector with jumper cable).
Same thing, 4L doesn't engage. No lights on the dash.
Leads me to believe something failed underneath, and happens to be around the time of my switch install :(. -OR- Anyway possible the switch could have locked something up? or did any damage?
How common is it for the Actuator or 4L indicator switch on the t-case to fail?
