I'm going bigger with a new tandem atv trailer with eclectric brakes. I have a 04 250 5.4l so towing is not an issue I'm just not sure which controller to get. Any ideas without starting a controller war. LOL
grafekie, my Tekonsha P3 instructions never mentioned hydralic trailer brakes, nor did it ever show how to hook it up to the hydralics. of course, I might have lucked out and gotten the one just for electric trailer brakes. FYI: the item number on the box is 90195.
The P3 doesn't hook directly to the hydraulic system; it drives an electric pump that supplies pressure to the brakes on electric-over-hydraulic systems.
Ditto Steina... the regular Prodigy can't handle electric over hydraulic brakes, but the P3 does. Other than that they are the same controller, except the P3 is far more confusing and more expensive.
Electric over hydraulic brakes look and act like regular electric brakes as far as the truck is concerned. The hydraulic system is entirely self-contained on the trailer. They aren't like true hydraulic brakes, where you hook up hydraulic lines to the truck and all that. They are generally only on the largest of trailers (if you go horse trailers, generally optional on 4H rigs and aren't standard until you get up into the 10k empty trailers).
Steina, help me understand...... if I had hydraulic brakes on my trailer, how would the P3 know that? would the electric pump that pressurizes the brakes be hooked up to the auxillary wire in my 7 pin hook-up? is this pump normally located on the trailer? I don't have that size of trailer... and really don't think I ever will...... all I tow is a 15ft vintage travel trailer that barely weighs 24oo lbs.
you know, you'd think somewhere in all the multi-launguagei nstructional manual, Tekonsha would have mentioned the P3 was for hydraulic over electric brakes - but, darn - I can't find it.
my answer to the confusion of setting it up - let my 15 yr old cousin do it... you know these kids - they are much more techno than we older folks are.
The P3 would power that trailer-mounted pump instead of the brake magnets in a regular electric set-up. Most hydraulic trailer brakes are powered by the master cylinder on the coupler (surge); the electric-over-hydraulic systems are pretty pricey so are not very popular.
