There are four available circuit diagrams, and I have yet to find any Pantera that matches any of the four perfectly. Most of us have several different diagrams, and we annotate them as we find differences in our personal Panteras. OK; in one diagram marked "6/15/72", there is a red wire piggy-backed to an orange wire on one of the 'parking lights' in the tach. This appears to be the only red power wire on either instrument. DeTomaso likes to piggy-back wires... The absolute worst that will happen is, if its wrong, a fuse will blow, and they are readily available as "GBC'-type fuses at any Pep Boys or Kragens. Good luck at Laguna Seca.
