Dominguez, who hails from Paraguay, will contest his first full season in the one-make series, which kicks off on Sweden’s snowy roads next month followed by events in Croatia, Italy, Estonia and Greece.
On top of his Junior WRC plans, the youngster will also strive for success in the WRC3 championship with additional outings planned in Mexico, Kenya and Chile.
The announcement comes off the back of a successful 2022 season, during which Dominguez showed blistering speed - capped off by a class win at EKO Acropolis Rally Greece.
“I am very excited,” the 22-year-old exclaimed. “We are going to prepare for every Junior WRC and WRC3 event by driving a regional rally beforehand. This will give us the confidence to complete each event with the results we hope for.”
