^ I've checked all of the vacuum lines and they are good. Vacuum to the EVR is good. There is no vacuum coming from the EVR. I would like to know how to manually activate the EVR. If I'm seeing a constant power KOER then what is the other wire? The EVR has nowhere to ground out to complete a circuit. This is not a ground wire?
I'm just gonna have to just get the truck back. I can only get it on Thursdays though. That's why this is such a bitch. I don't have any time with it.
