I have looked at the wiring diagrams and I cannot see any mention of the DTRL feature, it is mentioned once as far as I can see in the section on lights but no info.
I understand that Canadian Tire uses some part that I read on this forum cost $30, this seems too cheap for a headlight switch, but the price maybe wrong. If it is the switch that is changed then a quick study of its workings may give you a hint at what can interrupted by a switch. If it is another item that is added then find out what and were it goes and see if it can be switched it on and off. Search this forum and look for someone who imported a Xfire and PM them for what exactly was changed or added. There was a few threads where importing and DTRL's was discussed. I will search and see if I can find the thread(s) I am talking about.
Edit, I found this,
