Attempted to put in a new radio yesterday, I didn't know they made connectors for the old factory wiring to the new so I cut and crimped the wires together in accordance to how a connector I bought afterwards showed the wires. I turned the car on with everything set up how it should and there was no power. Out of frustration I stuck the yellow battery wire into the lighter socket and it cut on for a while but I need it to work with the radio wires.
What did I do wrong/what can I do to fix it?
