2000 Jag S-type V8 Help

My check engine light turned on and I found out through Auto Zone that the problem is the injector control relay (Code# P0065).  I don't have a mechanics manual and Auto Zone said they need to know which relay it is, specifically, so they can figure out if they have the part.  They said relays are normally $15 - $20 and if they can get it then they'll replace it for me for free.   I really don't want to go to the jag dealer.  I am trying to locate a manual, but thus far no luck.
