I installed the SuperWinch 4500 with the KFI mount and cable stop. Not that hard to install, just time consuming because you have to figure out where to mount the components and route the cables. It also requires some dash drilling to mount the switch and/or wired remote.
Basically, you take your front bumper off, mount the winch to the mounting plate and then reinstall the bumper incorporating the winch and mount into the bottom of it. The kit comes with some replacement bolts for where they are needed. The original plan is for the solenoid to mount near the battery with a set of short red and black cables and then the winch is to connect with the longer set of blue and yellow cables. Under the seat near the battery is not a great place to mount the solenoid, so I mounted it under the hood and then used the short cables to the winch and the long cables to the battery. Worked out fine routed underneath above the skid plate with a bit of zip tying to the frame here and there.
I drilled the dash with a 1" paddle bit and mounted the wired remote plug there. I keep the remote in the glove box and plug it in when I need the winch. Didn't mount the switch at all. Works fine.
Only weird thing is the install manual for the SuperWinch says straight-up not to mount the winch inverted. The lower mount method with the KFI stuff is just that - inverted. Several folks assured me it would work fine and it seems good to go. Haven't really worked it hard yet.
The KFI winch stop is a pain to get over the end of the cable, but it can be done with a some patience and brute force. I'd suggest sitting it out in the sun for a while first if you can to soften it up a bit.
