1. Carefully remove the locomotive’s shell from the frame. Notice the orienta-
tion of the shell to the frame so that you can reinstall correctly.
2. Remove the 6 pin analog shorting plug and in its place insert the DZ125IN
decoder with the correct pin-1 orientation. The DZ125IN has 6 pins that
insert directly into the 6 pin socket (NEM 651 type) on the locomotive’s
PCB. The DZ125’s small size allows the decoder to be easily installed in a
variety of European locomotives. For the Kato EMD Class 66 example, the
DZ125IN should be inserted in the socket as shown in Figure 2.
