yes you need them. and thats all i am going to say. certain things can be removed for certain reasons. and guess what? if you dont know how it works then you shouldnt be removing it.

EFI relay supplies electrical power the FUEL INJECTION SYSTEM. If you are going carbed and a magneto, go for it.
The resitor you don't need, nor the relay that activates the resistor... if that's what you're refering to. the one that drops 3 votls unless you're WOT.
not sure if that's what you're talking about or not *shrug*

Thanks for the advice! I was pretty sure that I don't need a fuel pump relay, I can wire that to ignition.
The thing with the EFI main relay is that if I don't need that, then I don't need any part of the fuse box. My quality of life would improve if I can just give the EFI harness 12v directly and not deal with wiring in a relay.

let him do it. eventually, if the car dosnt get sent to the wreckers, someone else is going to have to fix his mess.
Boso: Relays are your friend run them on EVERYTHING as none of the Toyota switch gear can handle current.
Lagged: Nah I'd rather help him succeed with this project as it'll make a fun car!

heh, whats the time difference over there? it must be morning or something because im too tired to have that perspective. maybe in the morning (here) ill be a little more helpful.
Ij: Thank you for the straight answer. Now I know I will wire in the fuse box and just deal with it. Its not that hard, it just would have been a lot easier with out it.
lagged: I have not made a mess of anything. I asked about it first becuase obviously I didn't understand. This is a forum afterall.

Boso: Toyota and most car makers went light duty switch gear,thin wire and relays many years ago so the days of wiring a load to a switch are long gone unless you use aftermarket switch gear and heavy wire!
boso, you can check out a thread i posted in the reference section about the 12v fuel mod. it eliminates the fuel pump resistor and relay, and sets up the fuel pump with an aftermarket relay and heavier wire. works like a charm.
