    A good enough decoder given the price but in my experience it has not been a “drop in” installation. The speaker is too tall and the baffle had to be cut and so far I have not been able to get the body shell to snap down over the tabs because there is not enough room for the decoder which rests on the top of the frame, and not inside it and it definitely will not fit the tabs on the motor mount.. Also, I have not been able to get the lights to work – not on the headlight contacts or the auxiliary light contacts either. No combination of soldering to the contacts will work. So, while I’ve not had a problem with other XL Systems decoders, this one has been a disappointment.

    I found that the output for the lights is about 3-4 volt Which will work for leds. The only way for lights to work is pushing the”0” button. It turns on both headlight and auxiliary lights. The function “3” key does not control auxiliary lighting for some reason. When headlight is on the auxiliary lighting is on how ever it flashes like a mars light.I don’t see any other way to reprogram the auxiliary lighting. I wanted to add a backup light. But appears to put of the realm with This decoder.
