need fuse box diagram

Either a short in the system, or something is pulling too much current. Perhaps you have a bulb that's out which is causing undue stress on the rest of the circuit, or else it's got a problem with one of the resistors/etc. in the printed circuit for the gauges.

Has anyone changed the factory radio and or adding anything to fuse box without diode protected relay .found several radio installation s that were causing feed back into PCM and IDM constant drivability issues good luck if you find anything using power off fuse box rest assure it's not protected from voltage spikes and voltage drops causing more than just blown fuse
