My Stehl tow dolly came with electric brakes. The local trailer dealer where I bought my controller installed the controller. My rig only had the four wire flat plug so I had to get seven pin plug, wires and everything installed. The whole works came to a bit over $300.
Considering that on a couple of occasions I have gotten trapped in a filling station and had to back a few feet before swinging out, I was glad I did not have surge brakes.
