I put an after market Kenwood radio in recently in my 2002 f150 and it blew the cluster panel lights .I lived with it but then I put new door speakers and subwoofers in and was driving down the road with the windows down when all of a sudden everything electric shut off .it blew the fuses to the dome lights and the power windows. I went to the auto store and got fuses for the cluster lights and the power windows and it fixed that but when I put the radio back in and turned it on and it read that there was a miswire and to rewire the radio and turn back on. So I checked the wires and everything looked fine so I put everything back together .And the weird part is, I could take the keys completely out of the ignition and turn on the parking lights and the radio would come on. And the radio worked while in accessory mode with the keys in the ignition halfway turned but when I started the truck the same error code came up on the radio. So I tried something weird and took fuse 18 out which is the fuse to the cluster panel lights, and the radio worked fine all the time now. But now whenever I have the volume up a little bit and there is a bit of bass from the subs the odometer and outside temp gage (which are digital) flicker and flash like crazy, and the cluster panel lights are still on very faintly even though there's no fuse for them and the lights are off. Please someone help me figure this out. I've never seen anything like this and I'm scared my truck is going to end up in flames .

 

Welcome to the site..

Might be easier if you were able to tell us what wire/tracers you tied the aftermarket unit in to..
As well as the function wires from new audio unit in to the trucks harness.. Not knowing what you tapped into, anyone's guess.. Certainly sounds like a component/circuit mismatch..
