Towing brake brain, what to use?

I was wondering what brake controller to use in my 2008 Tacoma?
If I wanted to increase my trailer size I think I will need one to operate the trailer brakes.
What unit is good?
How hard to install?
Thanks for all the input!

 

I have a Prodigy P3. I bought the Toyota adapter and it plugged right in. Since I have the tow package, the plug was located under the dash above the dead pedal. Mine was pushed way up into the dash so took a little wiggling and swearing to pull it down. I've been really happy with the P3. Easy to set up and easy to use.

 

I ended up mounting mine to the little drop down storage cubby next to my left knee. I just screwed the P3 mounting plate right to that little plastic drawer but there are many mounting places. Do a search here to find other spots.

 

Be sure to get an inertia type brake controller, not a "time based" or "proportional" controller. Google the difference, it takes more to explain than I want to type out, but once you understand the difference if how they work, you'll be happy to spend the extra money.

 

I liked the write-up on those and was researching to see what others' experience has been.

Exactly the question I was trying to get an answer to. Perfect timing on this thread!

However, I do have a question. According to this write-up:

The Tekonsha Prodigy P3 uses an "inertial" sensor for "proportional" braking. Can you help me understand how these two things would be separate, while in this unit they go together?

Thanks!
