I installed the Pro-Mark in my 825i and absolutely love it. I was able to test ot last week. Dididnt want to start the gator the other morning just to load it. Used the winch and pulled the gator with the bed loaded with a 40 gallon sprayer full flawlessly.. Winch is very well built in my opinion. I wanted a warn but could nt justify twice the price for what looked like the same winch. The promark has a lifetime motor warranty as well..
Wasnt bad at all, a normal person would have probably been done in a few hours. It took me all day on a saturday afetr checking and triple checking wire routing and adding protective sleevs on the wiring to prevent rubbing and the tie wrapping and securing the wiring until i was content. According to my wife im a little OCD but in my opinion im just detail orientated..
Then I did the install of the remote outlet and swithc the next day.
I installed a Badlands 2000lb winch. It fits right on the plate of my 550 S4 just had drill out the holes to 1/2. It might be a bit light but the 550 S4 weighs 1440lbs so figured what the heck. There were some pretty impressive videos of this winch on You Tube you might want to check out. The price is 54.99 on Harbor Freight's web site. If you want to install the fairlead you need to buy the mounting plate $3.99 from Harbor Freight. I ordered one so I can mount the Fairlead. I will warn you it is NOT FAST.
07/24/2013 I got the mounting plate from Harbor Freight fits perfect just had to drill out 2 holes to 1/2" to except the stainless bolts I bought. I had to extend the wiring also to reach the battery. I mounted the switch inside the glove box with velcro. It looks good but not to sure what will happen when I need it. I mean my daughter bought it for me so what can I lose
