The DO link before "contact" is called "ignorance" in several discourses.
One example is SN 22.81 the Parileyya Sutta:
[Last two sections.]
"Or he doesn't assume form to be the self... but he may have a view such as this: 'This self is the same as the cosmos. This I will be after death, constant, lasting, eternal, not subject to change.' This eternalist view is a fabrication... Or... he may have a view such as this: 'I would not be, neither would there be what is mine. I will not be, neither will there be what is mine.' This annihilationist view is a fabrication... Or... he may be doubtful & uncertain, having come to no conclusion with regard to the true Dhamma. That doubt, uncertainty, & coming-to-no-conclusion is a fabrication.
"What is the cause, what is the origination, what is the birth, what is the coming-into-existence of that fabrication? To an uninstructed, run-of-the-mill person, touched by what is felt born of contact with ignorance, craving arises. That fabrication is born of that. And that fabrication is inconstant, fabricated, dependently co-arisen. That craving... That feeling... That contact... That ignorance is inconstant, fabricated, dependently co-arisen. It is by knowing & seeing in this way that one without delay puts an end to the effluents."
