Decoder installation using Train Control Systems MC2

 Fig 1: Remove the couplers (held in by snap clips) and the rear cab handrails (this is so you won’t break them when the cab separates from the floor).
vofig2
 Fig 2: Gently squeeze and rock the hood off the chassis. It may help the first time to push one or more of the tabs from the bottom.
vofig3

Fig 3: Remove the cab/floor assembly. If you want to replace the yellow LEDs with Golden White LEDs, see Figure 4. If not, skip to Figure 6.
vofig4
 Fig 4: The cab comes off the floor (this is why you remove the handrail first) and you can see the LED leads sticking through the cab wall.

Fig 5:  The interior snaps out and reveals the LED retainer. Remove this and the LED and bend the leads on the replacement the same as the stock part. Make sure to match up the lead frames (the part you can see through the plastic of the LED) so the polarity is the same. Replace the LED and retainer, and then the interior. Put the cab back on the floor. The headlight (not shown) has a black retainer that comes out fairly easily. Bend the leads of the replacement LED the same as the stock part, and replace. The two resistors on the board have to be replaced with 1K ohm resistors to keep from burning out the Golden White LEDs (they run on much less current than the yellow ones).

 Fig 6: Install the decoder with a harness and NMRA plug. I made a custom harness to put the decoder in the front truck well so the weights I had already made to fit over the board would still work. You can also put the decoder on either side of the plug with a shorter harness. I added (not shown) a piece of Kapton tape over the decoder so it would stick to it and keep it off the front truck. Reassemble the loco and program.
