Question Regarding Spectrum K4 Decoder Interface

[ferroequinologist]

Hello,
I'm looking to purchase a sound decoder for my Bachmann Spectrum HO scale K4 (which I purchased over 10 years ago), and as I have no experience in soldering, figured buying a decoder with a plug would be the best option. With that in mind, I'm wondering if anyone can confirm the number of pins in the DCC decoder interface, as I want the number of pins on the decoder to match what's on the locomotive. As a point of reference, the particular K4 I have is Item # 84014. Thank you very much.

Better watch some videos about decoder installation. It's a little more involved than just plugging something in.  Plug and play is a myth.

Soundtraxx has an entire library of videos about anything that could be possibly involved with decoder installation.  Including one about how to solder which you probably ought to watch.
