To my best understanding moha (मोह) is enchantment and kaama (काम) is desire. However, I am looking for textual references differentiating the two!
Sri Krishna says in Gita about desire - काम and delusion - मोह.
ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते।
सङ्गात् संजायते कामः कामात्क्रोधोऽभिजायते।।2.62।।
In the case of a person who dwells on objects, there arises attachment for them. From attachment grows hankering (strong desire), from hankering springs anger.
क्रोधाद्भवति संमोहः संमोहात्स्मृतिविभ्रमः।
स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति।।2.63।।
From anger follows delusion; from delusion, failure of memory; from failure of memory, the loss of understanding; from the loss of understanding, he perishes.
So desire - काम is the grand father of the delusion - मोह
