As I recall and it has been lots of years since I replaced my timing belt, I do not recall a timing mark on the aux shaft. Crank lines up with timing mark on cover, cam you can see through the plug in cover and it is at about 5 o'clock. Aline dist rotor with number one on the cap. Which looks to be straight out from the engine. Dist rotates clockwise according to the picture I am looking at.

I'll add that whenever I change a timing belt I put different color paint marks on the belts and pulleys. I then transfer those marks to the new belt. That way there is  misunderstandi ng vague markers that might have scuffed off, bent, broken etc.. I also take before and after pictures. It adds 10 minutes to the task and eliminates 99.9% WHAT!!! - if later something isn't working right. I'm getting too old to remember..., if I remembered.
