I installed the same kit on both my '03 and '05 Jeeps. It was easy to install, and worked reliably on both Jeeps. I used the switches that came with it, like you did, on my '03. Back then, the instructions had the switch pod mounted over the hole left when you removed the manual window crank. It was right where my knee leaned against the door and I was always unhappy with that. It looks like your kit has a plug over the window crank hole, and the switches are mounted higher up, a much better arraignment.
The instructions still tell you to mount the switches where the manual cranks were located. I figured out that was going to cause a problem with my knee and also that it would be sort of difficult to reach, so I installed them up higher in front of the latch handle. That has worked very well and it is quite nice having more room for your knee without the crank handle (or switch). The plugs for the crank handle holes did not come with the kit. I bought them on Amazon.
