As of 6/6/2011 a new PowerTrain PDM is being offered on the Cascadia.
All parts are the same as the old one except for the shell base which no longer has the 4 prong buss bar or power stud and nut.
Trucks built prior to 6/6/2011 only had the option of the PowerTrain PDM with the four prong buss bar and the power stud and nut.
Trucks with a build date of 6/6/2011 or newer came with either the PowerTrain PDM without the four prong buss bar and the power stud and nut or the PowerTrain PDM with the four prong buss bar and the power stud and nut.
