Ok guys, So I was wiring up some off road lights and now my truck won't start. Theft light is blinking fast, oil pressure gauge going nuts radio went dead but is back on now. Please help I think I may have fried something just don't know where to start. Aslo makes a thud noise when the ignition is turned? 2000 f150 5.4 4x4

 

Your battery is probably dead.
