EZTSk Install Question

I’m getting ready to do the install of the EX Turn Signal Light/Horn Kit. I couldn’t really find anything on line with a video that gave much information on this kit. I can work through most of it but the big question is. What is the best way to get access to the frame area to run the wiring from the front to the rear? Should I drop the skid shield on the bottom or can I get enough access from removable panels on the interior of the cab? Any other things that I will need to think about?

I’m wore out from other installs this week and need some trail time so I’ll be doing this install next week. Thanks in advance.
