Which EOH System
 

I’m converting my surge brakes to EOH I’m go with the Hydrastar,they offer 2 complete systems. One is a plug and play system the other is a conversion system I’m not sure which one would work best. My truck has the built in brake system and 7 trailer plug.

Thius may help as I just went through it. If I did it again I would likely go Hydrostar.

Hydrastar Plug and Play, the only way to go. Also, depending on what year and make your vehicle is, might I suggest the system with the controller assist module (CAM) included. If I remember correctly, it was only $50 more. If you need one, it's about 1/2 price of the cost to buy it later. My'19 GMC is supposed to work without it the CAM, but for whatever reason, I have seen several later models that will not work without it. My system had it from my old '09 that required it. It works perfectly. The only two places I could find the plug and play (two years ago) was Carlisle and EasternMarine. EasternMarine was a little less expensive than the manufacturer.
