I have a 2022 mini 2529 RG. I am trying to install a Yakry back up camera. It is wired for a voyager camera. I cut the voyager plug to splice in the yakry camera but I am only getting 1.4 volts from the wires. I have the running lights on, connected to my truck and the truck running. Can’t see why would only get 1.4 volts, any ideas.
