So I followed your lead and looked up harimau on wiktionary. Then followed the link to *qari-maquŋ. The data source was listed so I followed that link and found a very nice resource. ACD combined with openstreetmap to show cognate sets on a map. You probably already know of it, but I thought I’d share it here because it really tied everything together for me visually.
The map for *pitu₁ (seven, or 5+2) is really cool (below is just a screenshot, hover over the dots on the actual map and it shows the language/dialect and the cognate word):
