Help with no power??

Mattax
Where does the white end
Plug into? The squared end with the round connector goes to the starter relay I assume? My swinger doesn’t have that so I can’t cross reference to my Chally! Thank you. I will Follow the wiring diagram tomorrow when we get back to it!
That's the fuseable link and main power supply to the inside of the car. Originally there would have been a wire going to the bulkhead connector that had the other half of that white connector. If the wiring diagram that Mattax posted is accurate, that main power wire goes into socket 16 (one of the red wires highlighted in the diagram). If you follow the wire back, you can see the connector for the fuseable link section, and then the starter relay connection end.
