Bought a used boat that didnt have the safety cable installed. Virginia requires one to pass the yearly trailer safety inspection. So I ordered a new one from Ranger, $19, not bad. Installed it tonight and let me tell ya, since I have never done it before, it was slightly difficult. Used dowel rod to keep the rollers in place and slid the whole thing out the back of the swing tongue. Once I got it out and seen how it all works, it was much easier to understand. All in all I took 30 minutes, start to finish. Now that I have done it once, I could do the whole job in ten minutes now. Its not that bad. If anyone has one of these to do, hit me up if you need some pointers
