Steering box leaking?

Just swapped in my '99 Dakota box, now the damn thing leaks.
I can't tell where it's coming from? How do I stop the leak?

find leak,repair leak.

lol - that was good above. anywho, what about the o-rings on the pressure and return fittings? did u use new ones? maybe also use some teflon seal on the threads there. if it's not leaking from one of those lines...well, that leaves the box, and as painful as it is u may have to take it off to get a good look...
