Self install is moderately easy

I went with the XT25 over the RT25 because of the synthetic rope.  Being that the main reason I was adding a winch in the first place was to raise and lower a new plow, the synthetic rope is a must because of the angle of pull and the constant back and forth is tough on the wire rope.

I installed this winch on a Suzuki 700 Kingquad.  The install was pretty straight forward.  The sequence is the same no matter what you are installing it on, not necessarily specific to the Kingquad.  1.  Mount the winch, No matter what you are putting it on, you usually need a mounting plate.  I bought one directly from Warn, which is a little more money, but the bolt pattern and front lip for the fairlead roller are lined up perfectly.  Some others are universal fit.  That's what you'll get, fits with universal fitting mounts.  2.  Mount the contactor.  Probably the toughest part.  On the Kingquad, there is a space under the seat perfect for it with predrilled holes that line up perfectly.  3.  Connect the control rocker switch to the handlebar and run the cable to the area whereever you mounted the contactor.  Plug it in, its idiot proof, there is only one obvious place to connect them to the contactor.  The seperate red wire is tapped into a wire that is only powered when the key is in the AUX position.  I chose the Aux headlight.  4.  Make the power connections.  The Kingquad has a pre run conduit that runs from under the seat to the front end where the winch is mounted.  Made this easy.  Others makes and models have the same feature.  Two cable connect to the winch, two cables connect to the battery positive and negative.  That's it.  Test it out.

After a week of use, I am very, very pleased with the operation.  Its smooth, quiet, and solid.  Yanks the plow up and down very smoothly.  Yanked me out of a big mud hole with ease.  No problems at all.

I highly recommend this piece of equipment.

Simple to install, but probably will not stand the test of time and weather.

Cheaper than auto stores and easy to install for yourself as long as you know what you're doing.

not the easiest to install, but for the price you can't complain, reccomended for practice before you install anything more expensive

It was a little harder to install than I thought, but it works.

Installed fairly easily - didn't have to change cables.  Might be nice to include some kind of instructions or visuals.  Local mechanic showed me the basics and I was able to get them on without too much trouble.

Rather easy to install, had to do slight modification. Sound quality is ok but for $35 it was a good deal

Easy to install

I used bolts and bits rather than the screws, but that's just me.

I would like to say it is easy to install but it isn't at least for the casual DIY'er.  It can be done but because you are working with electricity, follow the directions closely and observe how the current switch is set up.  The unit was slightly bigger than the opening I currently had but it eventually fit.  Once put in, it works well.  I would put these in those rooms that people are in and out of.

Fairly easy to install.  Just be careful with your screw/bolts.  I tied my bold with dental floss to avoid losing it.  It helped to have a second hand available, too.

EASY TO INSTALL. DO NOT BUY THE INSTALL KIT AS IT IS NOT NEEDED.
