Adding a pic of your current DVD player (before removal) would help. I suspect that you have an aftermarket (not port-installed) DVD player based on that wiring but hard to tell for sure. A few notes from my recent experience with this:
-Many 100s got port-installed DVD players. This involved replacing the cubby by the passenger side 3rd row with a DVD player, routing wiring, cutting a hole in the headliner, and installing the drop-down screen. The port-installed player system has a Toyota part number and looks factory, but if you punch your VIN into Partsouq you'll notice your vehicle wasn't built with this system. This guide shows the port installation steps:

-To avoid trying to rig up a backing plate for the non-DVD dome light and to take advantage of the space for sunglasses or other small items,
@LJE created a replacement trim piece. This post and others within this thread show it:

-When I pulled out my 3rd row DVD player, I replaced it with an OEM cubby to regain some storage space and to avoid a potential source of parasitic draw. You can punch your VIN into Partsouq to grab the right part number for your vehicle. Here's a post showing the DVD player and its replacement cubby:

-Some 100-series had completely aftermarket DVD players; the extent of headliner cutting, wiring approach used, etc. may vary. Hence posting what's installed may be helpful.
