Electrical Problems - No EFI

Ok I have found that I do not have the 12v power from Ignition switch to ECU. I do have power from other pins.

I have checked the power from the 7.5A IGN fuse in the drivers foot well and I am getting 12 Volts there.

Somehow I lose the power in the transition from the IGN fuse to the ECU and I am leaning towards the Immobilizer as the culprit.

Studding a the wiring diagram a bit more, but if someone has done immobilizers before on a supra, where do you splice into the Ignition wire? I can't seem to find anything so far.
