Where does ECU wire 47 black white (great pin out list here SR20DET wiring ECU pins and description of wire colors (http://www.240sxmotoring.com/srwiecupiand.html)) Go for power?

I noticed it wasnt getting any power but my car was still running, but starting poorly.?? Im gonna wire the orange wire to the ignition harness to fix that.

Does ur car still have starter inhibit relay?
I did the orange wire trick an nothing
It was that relay I just cut it out and connected wires
then when it happened again it was ign switch it self

Sorry i should have made that more clear. I know what to do with the orange wire. Upon ripping apart the previous owners hack job wiring i discovered the ECU power wire (pinout 47) was not connected to anything.. Does it need power? if so where from? It hasnt been getting power and the car has ran.

my sr ran too but ever time i jammed the radio it would cut off
i used a relay an charged all the switch wires to ecu from batt
