controlling for sex/age in saturated model with categorical outcomes

Hello everybody,
I've attached a script with a saturated model for a categorical (3 categories 0,1 and 2). Now I am wondering how to know if I have to control for sex/age in my next analysis (ACE/ADEmodel). I guess I would have to add sex(i also have opposite sex pairs) and age(continous) to the saturated model and see if it makes a significant difference of fit if i drop them or constraint them to be equal.However, I have no idea how to get these variables in this saturated model. Do any of you have any tips where to find this or how to get started?
Thank you!
ps: Sorry if this al sounds like nonsense, as a student I am very new to the topic of twin analysis and the programm OpenMX (so also never used the old MX).
