Today while over at our transportation Department, I asked if they had honda manuals, since part of the fleet is accords. They were nice nice to look it up for me, and they said based on what they show in the pictures, and wire diagrams the difference is one relay, which is marked Canadian models only.
So they said that most likely, if you installed the relay, you would have DRL's in a US car, and that all the wires should be installed. I have sent an e-mail to my brothers local dealer, he lives in Canada, to ask them if this is a user installable part, since the local shop did not even know Honda made cars with DRL.
I will let you know what I find out from him.
