oh.....
it depends where that black/white stripe wire is. typically it's 12v ignition power but it can also be the ecu's back up 12volt supply via the ecu relay. i don't remember all the sr ecu pins off the top of my head but the power for the safc should be like the second pin over all the way to the right at the top. i will say that i've never wired in an safc2 power source onto a nissan's black/red stripe wire meaning that's not what apexi intended. go to
www.apexi.com and double check your wiring compared to how they tell you to wire it, then get back to me. gl
