So I finally tackled the project last week and now I have map lights that come on with the rest of the interior lights!! All I did was tap into the wire in the overhead TV screen I have for the back seats that turns those lights on with the interior lights and ran a wire in the headliner, around the sunroof and down through the front overhead console. To do this properly, you will need 2 diodes, one for each map light where this wire connects to, otherwise whenever you push the button for the map light to operate it manually, it will turn on all the interior lights (backfeed). I included a few pics of the install, I have more so if you need more info, hit me up!! If your lights don't turn with the rest of the interior lights like the newer trucks do, this is an easy and very useful mod to do!
For those wanting to do this mod, the diodes I used were Radio Shacks's part # 276-1653 which is a 25 pack of assorted diodes, any of those will work for this mod that's in the pack!
