All my gauges are working except my speedometer and my gas gauge. I cannot find a relay or a fuse to see if I have blown it or not. Also I installed a new radio and it quit working also. So what do I do. Where do I check for these fuses and relays.

The speedometer is controlled by the VSS (vehicle speed sensor) there must be a circuit fault somewhere ?

disconnect fuel tank sender unit elec connector .. turn on ignition(not start vehicle) if gauge indicates full .. replace sender unit ... if guage indicates empty .. there is a fault at the instrument cluster .. either faulty gauge or gauge grounded in some way ..

The underhood fuse/relay box is behind the battery ..
