Figured out the problem, now I need the part

[AcuraSamauri]

I have an 04 Civic LX. My daytime running lights just went out one day. When I turn my head lights on at night I have know rear taillights. I checked all the usual suspects only to find out that my daytime running lights control module blew (and that's as far as I know). I need to get the part. I've tried rockauto.com etc and I can't find the part. Unfortunately I don't do electrical work so I'm confused as to what I'm going to need/where to find it. I've been reading in a couple forums about this typical problem in 01-04 civics, but it usual starts with the head lights. Can anyone help me figure out what part/part number it is. I've been considering by passing the entire control module by running speaker wire from the fuse box back to the taillights, just to give me some time and figure it out. But I am affraid I might do more damage. I'm exhausted and frustrated! HELP!
Thank you!

The part # is most likely stamped/printed on the module somewhere, I would not tie into the tail lights circuit for the headlamps the wiring will not handle the extra load and they are 2 different type circuits (1 supplies 12 volts and 1 provides ground path)
