Mine is an 845 auto-wrap but the routing might be the same. There should be a series for porcelain spools that lead from the twine boxes to about 1" diameter tubes located on the front side of the bale chamber. Start the twine coming from the twine box through a tensioner located on the box and then through each successive porcelain spool. Finally drop it down from the top of the wrap tube and let it hang out the bottom of the tube to a point where it will reach the cutter knife located on each side of the chamber.
