I looked up the m2 pc loader cable and it appears that it transmits via an infrared signal. Don’t think you’re going to find many pc’s with an infrared port, but good luck finding the cable. You might want to try the obvious and contact AIM. Their service is always great. Consider looking for a newer used gauge, an M3 or M4. Don’t think that AIM’s Race Studio supports an M2 and you’ll really want to have and use Race Studio, whiich is free.
