Here is my installation...works so much better than the stock light.
I did not use a connector, but rather wrapped the wires to the bulb casing as someone had mentioned. Real clean fit if you take your time and ensure there is not excessive bare wire after.
I needed to add some additional wire (small gauge 16 or 18 will work) to lengthen the end leads (solder and tape), I then ensured the wires I used were neatly tucked behind the trunk mat.
The OEM light still lights up as well, although like others have said...basically useless.
This is one mod I am really happy with. It provides excellent lighting to the entire trunk.
