does the h3 have an oil/tranny cooler?

But if you want to know if it has an auxillary cooler, just look in front of the radiator.

wait you are saying i dont need a brake controller? i have a trailer with brakes and you are saying the brakes on that trailer work even without a controller?

No they won't work without a controller. There 4 wires bundled together under the dash by the tranny hump next to the light. Wire your brake controller to those and you will have trailer brakes. One of the tech's at my dealer got me the color codes.
