Sapar Stock Join Date: Aug 2010 Location: Perth Posts: 8	Testing stage 2 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.
