Does anyone know where I can find a cable to activate timer for a Canon EOS Digital Rebel XTi.?

or wireless.

Well, not a "cable" in freedom. This is a remote trigger. Build your own or buy http://www.covingtoninnovations.com/dslr/CanonRelease.html One: Why http://www.bhphotovideo.com/c/ product/12935-REG/Canon_2465A001_RC_1_Remote_Controller.html want a timer that escapes me … you can use the timer on the camera and start using the remote switch
