The plates go directly under that spot you pointed at with the arrow. Can you take an underbody shot? I tried seeing if I had a photo but I don't and I'm not home at the moment.
Can you take a photo and upload it here? I just installed mine a month or so ago. You won't have to relocate anything unless they did some custom wiring.
Just got the frame reinforcement kit from smittybilt for the trailer. Didn't come with any instructions. Would anyone who got the kit mind sending me instructions if you have them?
