Close. These Spike relays had me confused for a while. First you must think of them as 2 relays,each with one contact. Each contact connects its output terminal (M+ or M-) to either the 12V or the GND terminal.
When the light is orange both are connected to GND.
When the light is green M+ is connected to +12 and M- is connected to GND.
When the light is red M+ is connected to GND and M- is connected to +12.
When the light is off M+ and M- are connected to +12
The PWM cable can be confusing also as it is not really PWM. It is connected to a relay output on the Digital Sidecar. The black wire is tied to the negative. The red and white wires are connected to + 5 when the cRIO wants to activate a contact. I cannot remember which controls which.
Here is a link to the manual:
