So are you removing the QSI units? They do DCC and DC and Gwire/Airwire.
If you have the wireless receiver plugged in, they get their commands from Gwire/airwire from the little receiver board.
Unplug the board, and you get DCC or DC from the track pickups.
Let me know what your goal is. I can use one extra receiver if you are giving up the Gwire/Airwire.
have you read my pages on my sit about QSI, Gwire, etc.?

I am all steam, the SD40's will not be staying. The goal is to sell off the diesels and keep the steamers. The locos need to run correctly or they will be sold for parts. Basic analog DC operation is the goal with lights and sound.
When I checked out all the locos that came in several boxes, (4) ran on DC. This one did nothing, I started playing with the GWire and got sound and some movement front and back. I saved it for last. Now, I put it on the same test stand and get nothing. As mentioned, I unplugged the receiver, still nothing.
Checked the test track - +20v forward -20v reverse.
Here is where it gets really weird, when I check the two power feeds into the decoder (the two outer screw terminals) it measures 0 volts. I removed the wires and checked again, 0 volts.
Next, checked each lead to the track. Each one shows 0 volts to the near track AND each one shows +19.v to the far track. Same polarity.
Who ever did the install soldered one wire to the motor switch terminal on the main board, the other wire is soldered to a leg of a motor diode.
Neither motor connection is plugged into the main board, both motors are tied together and attached to the decoder. The front pickups plug into the main board.
Attached is a picture of the receiver, is this what you are looking for?
