1992 MX-3 electrical
 

i have a few issues. I have no instrument cluster lights. Thinking rheostat switch?, I have no interior lights when I open either door when the overhead switch is on door. Also i am having issues with my fuel pump. Previous owner hotwired the fuel pump to the radio fuse. I have no power through the harness, the engine and fuel pump relay work fine, but i cannot find the inline fuse to check it. Anyone else have these issues or have any ideas?

*UPDATE* found out in wiring diagram through a chilton book there were 2 relays. The main relay was bad, so i found one from a miata at a local yard. worked fine for a while. Cleaned up most of the wiring mess. But still no luck on the interior lights
