<<General House Wiring - To start need to install a new rearview camera and some 12V power outlets & Lights. Where is the main wire run to the back located - ceiling, through/under cabinets, walls? Under compartment lights wiring access through bottom of compartment? Ceiling lights and speakers wire runs?>>

First determine if existing camera is wired/ wireless? Then if existing cable compatible w/ your planned camera, or adapters available? If going wireless, easiest to just tap running lights for camera, then light switch controls camera power. To ADD interior lights or 12vdc outlets, first make sure incandescent converted to LED, then TAP existing light wiring, prewired/ prefused and plety f capacity for additional after conversion. HOPE this helps and LUCK to ya.
