How to implement the transfer of user data to GA through the Tag Manager?

Question

JavaScript

There is a one-page site, product order forms are sent via ajax. At the time of submitting the form, the variables already contain all the data about the product that needs to be transferred (name, price, color). GA is connected via Tag Manager, e-commerce support is enabled. Please tell me how to correctly implement data transfer to GA in such conditions after a successful form submission. I understand that you need to write something in the success ajax event? Direct where to dig. Thank you!
