When I click the link for Kato N Scale GS-4, I get this:
All other How T threads work fine.
Ah, I just figured out that you are looking at the DCC install index sticky thread.
Yes, the GS-4 link is mangled:

@Ian MacMillan or one of the other mods can fix it.
But keep in mind couple of things:
1. That thread is 13 years old. The decoder and speaker technology has advanced quite a bit since that time.
2. The early GS-4s had a design flaw which will blow up your decoder. The way the motor subframe was designed the rear driver could short the track voltage to the motor which would damage the decoder (despite of the built-in protections some manufacturers claim). That would be a $100 mistake! Once the problem was discovered, Kato offered a spacer set to be slipped between the driver and the frame to prevent shorts. The subsequent runs of the model had a redesigned frame which did not have that problem or require the spacer.
If you have a model from the initial run and it does not have the spacer installed, I would be leery of installing the decoder. I don't know if Kato still has those spacers available.
