My ‘95 has a Hayes Micro Control and my Y2K has a Tekonsha Sentinel. Both are inertia-type controllers, rather than time- delay types. Both will control from one to four axles. Most other inertial controllers are made for either 1-2 or 3-4 axles, and you have to choose which to install.
Among electronic brake controllers, there are two basic types, inertial and time based. Adjusting an inertial controller can be complicated. Time-based controllers are much simpler and easier to set, but they do not provide the versatility of the inertial units.
The time-based controllers simply increase the trailer brakes the longer you have your truck brakes applied, no matter how hard you are pushing on the pedal. I don't want that type, because it will not: 1. smoothly release the brakes and, more importantly, 2. apply full trailer braking the instant the truck pedal is depressed. It should be obvious how this could be a real problem if you need to stop in a hurry.
An inertial controller measures how fast the truck/trailer combination is decelerating and sends a higher current to the trailer brakes when the deceleration is higher. These controllers are adjustable for maximum current (to allow for different trailers) and sensitivity, which sets how much signal is commanded for a given deceleration.
My favorite is the Tekonsha Sentinel. It is easier to adjust for the various trailers I tow (empty flatbed to 14,000 lb. fifth- wheel) as well as providing more sophisticated monitoring. My Tekonsha discovered a problem with one brake on a brand new trailer that would have otherwise gone unnoticed until something drastic occurred. I don't know of a better controller.
