Need help with my SAFC2 power wire...

I wired my SAFC2 up using the N3-B diagram in the instruction book, and everything works fine except the power wire. When I ran the power wire from the AFC to the wire coming from the ECU that the book told me to, the AFC had power even when the key was switched off and removed. Without thinking of negative consequences, I just ran the AFC power wire to the power wire that goes to my cigarette lighter, and it worked fine for a week.

Today the cigarette lighter fuse popped, so now I have to find something else to wire it to. Which wire coming from the ECU can I use (if there is one) and if not is there any other ignition switched wire I can get power off of? Thanks.
