ecu control relay

got a 91 excel i'm troubleshooting a problem with the ecu. Does anyone know where about in the car the ECU control relay is located at?

Right now the ecu keeps frying circuit traces like fuses on the two 12V hot leads to the board. I've also noticed that when i turn the ignition on, i don't hear the fuel pump winding up. Both the ecu, fuel pump, and fuel injectors go through this relay, i'm hoping thats my problem...

Also anyone with a Chilton book, the electrical schematic keeps refering me to "See Power Distribution" when i come to a Hot At All Times lead, does anyone know what page power distribution is on??? I can't find it.

Thanks!
