I'm looking to buy a Duramax again, after having sold mine a few years ago, with many regrets after the fact. Anyways, I had bought a Brakesmart controller while they were still in business but it appears that they're fully out of production at this point? I saved the controller itself when I sold my truck, but don't have the wiring harness or fittings that were in place. Any ideas on where to find such? I guess I can check eBay every so often with high hopes. Thanks!
