Hey guys, just had a 2jzgte swapped in my 89 supra. I'm not sure what the wiring guy did (probably should've went Dr. Tweak) I'm having trouble figuring where he installed the EFI fuse. I know our EFI fuse was a 15 amp fuse and the new one is a 30 amp but I'm not sure where it is. Does anyone have the wiring diagram or know where it is in the circuit so maybe I can try to locate it with my meter?

The efi fuse should be in the same fuse box under the hood. There's no fuses on the harness.

I figured that would be the case however the EFI fuse on the old wiring was a 15 amp fuse where as the EFI on the 2jz is a 30 amp. Also I pulled the fuse to reset my ecu and it did not clear the codes.

My 2jz swap is wired through the original EFI fuse setup and im still running a 15amp fuse with no problems.

There is no fuse in the wiring, It is in the fuse box. unless you or someone else wired in a fuse inline.
