Alright so I swapped out head units this weekend (same maker so all I had to do was plug it in) it was a little bit longer so it may have hit something behind it? But after I got done I went to start it and I get full power to everything except the things that seem to start the truck. When I try to start it a Bosch (#500121) relay clicks once and the truck does nothing, doesn't attempt to turn over or nothing the fuel pump doesn't even turn over. I tried cheating it and starting it with just a wire straight from the battery to the truck, but the only thing I managed from that was turning on the fuel pump?? Any ideas please help out.
If I forgot anything I'll add it.
