Hey Tom,

I took a look at your 2018 Tiffin Allegro Red brake controller options and I was not able to find a plug and play harness for that motorhome. We do have a universal harness from Draw-Tite # 20127 that would need to be spliced into your motorhome, and then would plug into a Draw-Tite or Tekonsha brake controller. I did not see a harness for a brake controller that was a plug and play for your motorhome so it would need to be spliced.

What brake controller have you been using?

No brake controller needed. Just the harness. Can I send you a picture of the plug under the dash?
