Hmm, those frames look different from other Krauser frames that I've seen before... I think someone else will have to help you, but basically, the metal tabs on the rectangular frames goes at the back, and the latch at the rear or the panniers clips onto the tab. I would assume that the long metal bars with the curved/bend ends attach somewhere along the lower part of the rectangular frames to the bolt on the bike frame just ahead of the passenger footpeg. The other bits must attach the rectangular frames at some offset from the subframe rails along the lower edge of the seat in some fashion.. Sorry - this is very generalized..
