I have just got my superb S I running beautifully,and I open my next loco the proto 2000 sw8 (how do the gran childern now what to get you for christmas).
Well proto tell me it is to small to fit a plug into and just wire it up youself,i thought maybe a TCS M 1 would do the trick should i remove the board and hard wire the unit,it looks like the cab lights could be a bit of a chalange.
Remember that with Proto units, you either have to change out the bulbs or install resistors on the white and yellow leads (570ohms will do). They do make decoders specifically for this little guy, but it is always cheaper to hardwire (and more reliable, I might add).
NCE has an easy to install (but not just plug in) decoder specifically for these locos. The SW-SR. It repalces the existing board, and the wires connect to the decoder in similar locations as they did on the stock board. It includes a resistor for the rear light so you don’t have to dismantle the cab interior to pull out the old bulb, and ti has solder apds and a resistor already onboard to solder on an LED for the headlight. The decoder clips on tot eh mouting clips that held the original board.
