*RESOLVED* Need help with trailer brake controller

Is this the plug? It's the only one I can find and it fits the Tekonsha 3040-P connector.
However when I plug it in I'm getting no sign of life from the controller.
Even though the connectors fit, the wiring doesn't match up.

 

Do you have the towing package?

 

I thought I did.
I've got the 7 pin connector and a hitch.

 

Check the fuses then

 

Thanks! Yep, no fuse.
It's working now.
