DIY Foot well lights - power source?

[karloslatynos]

I am looking to fit foot well light in my Mk3. I have asked the dealer for sockets (no 1, 2, 3 on attached diagram) He said he never heard if any Yaris had foot well lights equipped (!) I even told him the owners manual mentioned foot well lights as an option. After he typed my reg number and we went to the diagram (the same one like attached) he informed me parts 1, 2, 3 are not applicable for my car so he cannot order them. I had the same situation (with the same uneducated mongol) when asked for EOM Daytime Running Lights kit. I have supplied him with the part number (PZ426-B0511-00) and the answer was the same: "not applicable for your car" To me its obvious some parts may not be applicable as they were not designated to my model.

Is there any other way to get those parts?
