Henríquez made his debut for El Salvador in 1986 and has represented his country in 1 FIFA World Cup qualification match.
His balance with UES was two wins, six draws and four losses, after being replaced by Brazilian manager Eraldo Correia in March 2011.
In June 2011, Henríquez signed as new coach of the Alianza reserves, after moving in from Segunda División club Topiltzín.
Henríquez signed again as new coach of Santa Tecla for the Apertura 2013 tournament, replacing William Renderos Iraheta.
In April 2015, Henríquez was hired to become the head coach of the El Salvador (Under 17) and Under 15 national football team.
Despite an initial streak of matches without winning (5 games), UES defeated Atlético Marte 1–0 in the Estadio Jorge "Mágico" González and began to add points that in the end were crucial to save the descent.
