EOH brakes are the minority and IMHO subject to some assumptions including a one size fits all controller mistake. My dealer installed an incorrect one, just didn't know it required a compatible unt. I don't know what is different, but on this topic I want the controller mfgr to say, EOH OK.
Singer Goose added some good info above too.
