I got a 3rail Sunset PRR N1 in. I'm working on the chassis first. I lubed everything, mounted and adjusted the motor. She runs pretty smooth now on just a battery.

So now I'm looking at all the original wiring and board. Someone gutted some of the stock wiring and removed the speaker. So I don't know where the speaker leads should come from yet.
There's an identical 2 wire receptacle on the opposite side of the board as the one shown on the far right above. There is a screw terminal post on the front that has the incoming pick-up wires already attached as well as the motor leads from the 4 wire engine harness on the far left end.
I started searching the internet for any info and all I got was a brochure stating QSI digital sound and Seuthe smoke.

Anybody know anything about this stock QSI board?
Ooops. it says cruise commander right on it. It actually works, just no sounds. So I'm guessing that it was a replacement and there's no sounds?
Off to find Cruise info. looks like a post that showed cruise commander 4.1
