I'll post pictures later, for my install I had the same design of kit as the OP, I used .250 disconnects and hit them with tin snips, they're actually a double thickness of metal where the metal is folded over, I nipped the edges which makes the second "layer" of metal fall off that is folded over. This makes the disconnect really thin and it slips in behind the metal piece in the socket no problem.
The other thing I wanted to tackle was not being able to install both lights symetrically if you want to mount the lights width wise. When I was test fitting the lights I noticed that the tube would fit in the "channel" everyone is running the wires through if the square ends weren't so big. I ended up using a trim saw and hacking off a corner of the square mount for the tube so it would slide into that metal. I ended up with two lights mounted across the width of the trunk, I'm losing a tiny bit of light from the part of the tube that is inside the metal channel but overall it works great.
