Steve,
For what it is worth, mine is routed just like Jim's. Loose, no clips. Routed near the front injector and down between air pipes 1 and 2. Follows loose like Jim's (no clips, behind the throttle linkage) down to where it looks like it joins the harness just inboard of the steering box - at least it looks like it connects. Mine is an early 72tii. Hope this helps - let me know if you need additional photos as Jim's are very good.
