Electrical, something shorted when installing new LED Cargo/Break center light
I have 1997 Dodge Ram 1500 Laramie 4x4 5.9l Magnum extended cab 6 1/2 ft bed gas truck with 162k miles. I bought new LED light for cargo/break center light. Wiring came wrong and now that light, interior dome light [with switch nor door switch, ECU plug under dash, nor radio work now. I bought pickup used and radio had been changed so not sure if wired same. I checked all fuses inside and under hood and all are good. I noticed that all fuses relating to these circuits were little black on connector pins. Could grounding have shorted if so any idea where. There are not many fuses and I was trying find a common fuse or point. Any help would be greatly appreciated.
