I am new to the forum so please forgive me if I am ignorant to how things work. I have a 2003 Discovery ll that I want to use to pull a travel trailer. Probably under 5,000#s. I will probably put a set of Coil-rite air bags on. Need to install Electric brake controller and Round 7 pin trailer plug. Is there some place that sells these parts in kit form specifically for the Disco? I already have the Flat 4 pin plug on the vehicle. Any other recommendations would be appreciated? Thanks!

 

There are quite a few threads here covering it. Google "brake + controller site:https://landroverforums.com" (no quotes).
