Okay that is done. Instead of taking it back to installer, I firmed up behind that flap of plastic to left of brakes on side wall in front of speaker. Used some blocking, leveled up the G Force, then made adjustments with RV attached. I'm assuming that the lights from the Demco brake notification thing, won't light up in stationary. For example G force all the way at bottom... cylinder was pumping brake when brakes engaged, lights on inside RV, turn signal also activated everything, moved upwards to less sensitive and things stopped but basis Demco's adjustment recommendations- lights won't come on in dash. I'm reading between the lines on Demco's instructions, but lights shouldn't come on unless you are in motion and pressing brakes in rV. So, I'm going to wing and prayer, and think this should do it. Firming up the controller helped immensley so you can tap on the G force and it won't activate on its own as it did before. Thanks for your help and suggestions btw.
If you out at night you'll be able to see if the lights are working. Rear parking lights should be on when the lights are on in the RV. Braking should work when the brake peddle is applied (while RV running). Good luck!!!
