Do you have the Toyota EWD? This is all laid out for you.
The EFI relay gets +12 on pin 2 from the 15 amp EFI fuse. The 15 amp EFI fuse is fed from the MAIN fusible link.
However if the MAIN fusible link was faulty, you'd have no headlights, no tail lights, no brake lights, various others, and no CEL with the key in the ON position.
The combination of the FSM and EWD is invaluable.

Thank you for posting this! I'll be working again on my girlfriends 95 tomorrow. I downloaded the 96 EWD and have been studying the wiring diagrams. I've learned a lot in the past week. Though one part still has me stumped... The vehicle will drive fine for 10 miles or so before blowing the 15 amp efi fuse. Once the fuse is blown, the 80 will only travel 1/4 - 1/2 mile before blowing again.
Jonheld, Thank you for your input. I appreciate your time!!!
