Because of the fact that this particular locomotive comes with the yellow wire function wired backwards - you need to reverse its polarity. You can do it two ways - cut the LED off and reverse its leads or simply remove the two black plastic wire holders on the DCC plug and reverse the LED polarity. The idea is to get the blue wire connected to the positive part of the diode (the short diode pin) and the yellow wire connected to the negative part of the diode (long diode pin).
Here is a close-up of the finished LL8 decoder installation.
