What's to the install of this harness? Mine comes in Friday and should be waiting for me when I get home from work, but I'll be busy all weekend and I'm an impatient man who wants to get this setup ASAP. I'll have about an hour-hour and a half window after work to get this and my headlights installed (and adjusted) so I was thinking about removing my grill and OEM headlights tomorrow night and just taking my wife's car to work so my Jeep is ready as soon as I get home. If I can't make this window, I'll be forced to wait until Sunday evening at the earliest.

Is it just connecting a lead to power, connecting the ground, routing the wires and plugging them up or is there more to it? Pictures of the harness aren't plentiful, but they don't show any reason I'll need to cut and solder anything.
