Dont\' Do It !!!!
I'm done with these type of brake controlers. I have the Tekonsha on my rig, and it's not worth the #hit it's made out of when going down hill with the gooseneck and blazer on the back, talk about a pucker...... Now keep in mind this is just my opinion. I just do not like what happens when the brakes start to get hot, the controler does not increase the power to the controler, it keeps throwing the voltage to the brakes, and thus, the feeling of very little brakes down a very long grade. They are ok around town, but on a long road trip, no thanks. Besides you have to adjust and readjust and adjust to get them to not either push the tow rig, or drag the tow rig.
I have done a %hit pot of reasearch on brake controler and this is what I just ordered.
Brakesmart Controler. It's real pricy, but in the long run in my opinion it's worth it. There is nothing worse than %ucking with the brake controler all the time. This one you plug it in and forget it, rarely if ever do you even have to adjust it. It adjusts for the trailer type and automatically.
Like I said, I hate screwing with the brake controler, and my days of doing that are shortly going to be over. As much as I tow the gooseneck around this price is going to be well worth it.
Don't waste you money on the other expensive controlers, read the above post and then make your mind up. I have read all the post on the Diesel towing forums and this controler is being touted by the guys that tow all the time as the hottest thing since sliced bread.
