Not sure of the use of the word "track" but the original DBW throttles had two plugs due to the external TPS the newer ones don't have. The old ones have a two wire pigtail for motor control of the blade and a three wire pigtail for the TPS. Trouble is, the newer ones with the internal TPS have two TPS built in so there are two signal wires, a low reference wire, a 5V reference wire, two motor control wires. You can reconfigure one to work with the other but since the PCM's are different (I think), you really need to know what you're doing AND have access to all the information (schematics, etc.) and know how to use the information.
