Difficulty:6 out of 10

8. Turn the engine over and remove the two screws shown in the photo. Caution: Do not loose the spring under the pilot truck.        

9.  Use a small flat blade screwdriver to release the clips holding the engine cab located under the engine on the firebox.

10.     Remove the engine cab by gently pulling it towards the rear of the engine.


11.     Remove the boiler by pulling it up from the running gear. Note how the red and black wires go in the groves under the firebox

12.     Cut off the brass tabs that provide power to the light from the drivers. 

13.  Feed the yellow and blue wire through the front of the tender next to the drawbar. 

14.  To help hide the yellow and blue wires, I used a black permanent felt pen to color the two wires black. 

15.  Solder the yellow wire to one side of the light and the blue to the other and insulate the solder joints (I used a liquid plastic normally used for dipping tool handles) 

16.  Partially reinstall the boiler on the running gear. Note: do not reinstall any screws.

17.  Route the yellow and blue wires up under the running boards. One wire will go above the power reverse on one side and the second can go above the air compressor on the other side 

18.  Using a flat blade screwdriver, guide the red and black wires back into the grooves under the firebox. 

19.  Route the yellow and blue wires into the same grooves making sure neither wire is rubbing on the rear driver. 

20.   Reattach the tender drawbar to the pin on the running gear and complete reinstalling the boiler making sure that no wires are being pinched. 

21.  Reinstall the pilot truck with the spring and the screw as well as the rear boiler retaining screw

22.   Plug in the decoder and reattach the tender shell. 

23.   Test engine.    Arrow points to wire leading to headlight.
