Just got the module and tested it out today on the truck. Works great and the truck drives very smooth now. My question is will it drain the battery? I had read in another thread that Range fixed this problem. The green LED does not stay lit when the truck is off. Yet on the back of the box that it came in it says do not leave it in a vehicle that is not driven for a few days because there "may be a draw on the battery in some vehicles."

I don't put a lot of miles on the truck so it would be annoying to have to remove it after I drive...
