The Sun Sets... |
A few weeks ago,
I towed a trailer a long way over various roads including some big hills with steep descents. It all worked out OK, but when I arrived home I noticed a significant amount of additional brake pad wear. Hmmm...Why was that? I'll tell you, I made a mistake. One that could have cost me dearly. I was under the impression that the trailer had surge brakes. These are actuated when you slow down the towing vehicle. They work pretty much on their own. Not the best solution, but they do not require any additional hardware. The trouble was, I was wrong. This trailer did NOT have surge brakes but rather ELECTRICALLY actuated ones. These REQUIRE a separate brake controller be installed in the tow vehicle/RV. If they are not hooked up, you have ZERO braking from your trailer. Your tow vehicle brakes do all the work. This is a dangerous condition! Well, hindsight is most always 20/20 so I ordered up a brake controller and installed it post haste! It's not all that difficult to do and may save your...well, bits you'd like to keep.

The P3! |
How do you choose what kind of controller to buy? Well, after some basic research, it boils down to two main types. Time Delayed and Proportional. To begin with, Time Delayed tends to be much less expensive. So what's the difference? In a nutshell, a Proportional controller applies braking to the trailer in the manner you apply braking to the towing vehicle. You gently slow down, the trailer gently slows down a proportional amount. You slam on the brakes in a panic stop and the trailer brakes get applied as aggressively. There is some setup involved to "tweak" the proportions, but it's not all that difficult. The time delay version simply waits a set amount of time and applies the trailer brakes at a single setting. The amount of delay and the amount of braking force applied is adjustable. Because of the way it is wired, there could be some pulsing of the brakes when you hazard flashers are on.

To me, it was a no brainer. I found the best Proportional controller I could, based upon reviews and features and ordered one. (I got the Tekonsha P3 and paid 115.00 incl. shipping) The install wasn't really difficult at all. It came with a wire harness with bare ends to splice into my existing wiring. Only 4 wires needed to be connected. 12V Negative, 12V Positive, A Ground and a single wire to the trailer brake wire in the hitch connector. While you can buy prefabricated harnesses with connectors for various vehicles, mine (being as old as it is and an "orphan") didn't have that option. The first three were easy and obvious. I did put an inline fuse rated to protect the wire on the positive 12V connection. The last one required me to run a wire from
the hitch connector at the back of the RV all the way up to the left side of the driver's footwell. That's about 26 feet of wire. Not difficult, I used good quality outdoor rated automotive wire and lots of wire ties (of the "zip" variety) to keep it tucked up out of harms way.
Next up is locating an appropriate spot to mount the controller itself. The instructions said I could mount it in essentially any orientation with ethe exception that proportional brake controllers need to be mounted inline with the direction of travel. Some vehicles have a spot that's made for one. Mine didn't. I wanted to be able to see the screen when I wanted to and have access to the manual braking lever and settings on the fly so I mounted it down under my dash above my left knee. Well a bit further outboard as I didn't want to smash my knee into it all the time! Believe me, that would be a really...well.. P.I.T.A. (figure that one out for yourselves!)

Nifty Little LED Screen |
Once connected up and mounted, the fun begins! On mine (which has a nifty LCD computer screen) I went to the setup page and selected the brake type. Mine were electric, but you could have hydraulic as well. Then you have to tweak the basic braking effect the controller applies. Your brake controller may be different, but mine suggests a default of "6" (somewhere in the middle) then you drive the trailer and tow vehicle 25 MPH and use the MANUAL lever to apply the trailer brakes. If they lockup go to a lower setting and repeat. If they don't, go to a higher setting. The idea being to set them up so it applies the brakes at a maximum level WITHOUT locking them up. Once that's done, use your tow vehicle brake pedal to make a few low speed stops to check the "feel." Mine worked out well on the first try.
There are a few other settings on mine, color and contrast of the display. A "Boost" feature that changes the amount of initial braking and force, to adjust for various weights of the trailer and the ability to store settings for 3 different trailers. It's also got a nifty Voltage gauge and lots of troubleshooting messages to let you know if something is connected wrong or malfunctioning.
Anything that increases safety and ease of use is all right in my book. This addition surely fits the bill!
