There in the plug that plugs into radio. They go under center console between seats to the fuse block under back seat. The data wire is the one that the power is intermittent. And I cant seem to find the wire that's hot when you turn key on.

Check the yellow wire, I believe that's the accessory power and the orange wire is constant (always has power).
