Ok I’ll try to explain this as best as I can in steps. Hopefully it makes sense. This is all for temporary fire up on my run stand. But it all applies to how it wires in the car. 1. You must ground every sensor ground located in J/C-1. These are black, and black w/blue tracer. Mine ran straight to battery ground. I also grounded the ecu. 2. I used batt+ From 50A batt fuse, large red w/black tracer, to a start button to trigger the starter relay this is yellow w/red tracer. 3. ASD relay, Fuse D, and Fuel pump relay trigger, all light green w/black tracer have to have 12v + with ignition on. I wired them together and to an on/off switch with batt+ fed from 20A engine control fuse, large red. 4.Fuel pump output needs to go to the fuel pump, dark green w/black tracer. 5.starter solenoid output needs to go to starter solenoid, large brown wire. And of course some pics for reference. Starter relay is missing in pics and needs to be there to start. I had to rob mine for something else. Everything else is there, and mine runs as it sits.
