One method that I've used with success is to go to the area that you intend
to tap into and open the wire bundle.    Then take a muti-meter or 12vdc
bulb in a pigtail with clip leads and hook one lead to ground and then take
a small straight pin and insert it into each wire one at a time attaching
the other lead to it.    Now go thru a sequence of parking lites, brake
lites, turn signals and see what each wire lites.   The small holes made by
the pin are usually self healing and then you should rewrap bundle area that
you tapped into after your connections are made.
