No power at gauges after putting wires to plug
 

So today I decided to work on the gauges on my 77 lemans. Keep in mind this are aftermarket and were fully functional before. So I decided to neaten up the wiring by putting it through a plug. Now nothing no power at all going through to the gauges. I've got everything connected except the speed sensor and lights. I've got no 12v at the plug so I'm thinking it's a fuses. But I'm at a loss!
