this pic it looks an awful lot like the PWM cable into the Spike is backwards. Make sure the black wire is near the "B" on the casing. Also check the Digital Sidecar end of this wire, to make sure Black lines up with (-) (Red with + and White with SIG).
Edit: According to your code, it should be in Relay output 4. Also note: the socket in Spikes and Victors can be a little funny - make sure the connector is properly and snuggly seated all the way down into the socket.
The solid orange light on the spike means it's being commanded to do nothing, which is certainly the case if there is no proper signal coming in.
