Since this is the closest to electrical, I might as well post my message here....I did a search and seems to be V1 has not been discussed before. I will be installing my V1 by hard wiring. V1 has a Direct-wire Power Adapter to be hard wired. What is the best electrical system that is in the overhead lighting & moon roof switches that would be switched off when the ignition is switched off and has 12 VDC when the ignition switch is on? Thanks.
