newbie Brake Controller

[Royalwapiti]

I just bought a Sprinter 255RKS (have not picked it up yet) and usually only tow utility trailers with my 2013 Tahoe, so no need for electric brakes.

I have a Hayes Lemmerz Equalizer III brake controller, been sitting in my tool chest for 14 years, used it with a Coleman popup back then.

Would that work for the Sprinter or has there been technology changes that would make me want to buy a newer design.

Are there aftermarket quick connects so I can make an easier job of connecting to the Tahoe?

Thanks
