    If you're certain the positive and negative connections are correct, the next place to check are all your fuses

    1. Did you reverse the battery polarity at some point when disconnecting and reconnecting the 12V battery?
    2. Check the DOME fuse since you say the passenger cabin lighting is not working. That DOME fuse provides power to several important circuits, it is not just for lighting.
    3. Do the headlights come on? If not, check the 12V battery cable tightness, especially the negative cable where it bolts to the body.
