I've got electric brakes on my trailer, but to get them to engage...i actually have to reach down and push/pull the knob on the brake controller mounted under the dash. Although it works just fine, I think it could be dangerous or risky if it came to a situation that involved emergency braking. Having to watch the road, hit the truck brakes, lean down...hit the trailer brakes....blah, blah, blah. Would it be difficult to just change out the module? or would I have to rewire a whole new deal? I would like to have the automatic ones where you set the gain and it hits the trailer brakes for you.
