If I can recall, the original Pit Wizard had a male socket on it and this could be damaged easily rattling in your toolbox. They changed to a female socket on the Novak Millenium Pro charger, it had the Pit Wizard software built in and you hooked it up directly to the speedo. Very good and easy to set-up. This uses the male/male lead.
Both are quite old now; I still have both in good condition and wish that Novak would make the new speedos programmable with the millenium pro, I hate trying to time my button pushing and waiting for the christmas lights to come on.
Part numbers for the cables are still on the Novak website, but they don't list the TC2 or Millenium Pro for sale any more.
You need the pit wizard adapter below.
