I started with exterior mounts, but then I thought...why? So then, I decided and left all the hooks under me seat and attached the loop part of the straps to them. Then, the rear straps run out the back on either side of the seat lock, and the two front run out the notches where the hooks would come out.
It's a snug fit and since its clips in and out, the only strap you see is about 4" showing.
I may not have a lot to say but it doesn't mean I don't listen.
