So I hooked up these 12 inch led tubes in this 2000 Cougar. I used the power wire and ground wire from the CD player like I usually do. I didn't think nothing out of the blue. Well I had all the wires hooked up to the toggle switch, I know they were right, 100% positive. well anyways I went to turn on the toggle and the lights didn't come on. so I figured the car had to be on so I turned the key and no dash lights came on, nothing came on and it didn't start, they only thing that was on was the dome light and the blinking security light, so I would like to know what I could do to get this thing running. I tried charging the battery, nothing. jumping off another car, nothing. I checked all the fuses and relays I could find and nothing, so please give me some advice. thanks you much.
