SR 2 plugs near battery wiring

[ska]

Hey so I've came across another issue with re-wiring the 2 plugs(big grey & small brown) near the battery. I've repinned everything (instead of splicing and soldering) color for color except I do not know where I need to connect this blue/redstripe wire(Main ignition power). My resources from this site here [click me] (http://docs.google.com/viewer?a=v&q=cache:L46dyFqk-iAJ:www.240sxtechdvds.org/files/S13_to_S13_SR20DET_Harness_Layout.doc+sr20det+swap +plug+%26+play+harness&hl=en&gl=us&pid=bl&srcid=ADGEEShN6XJV-mzOQpqmPepa2qqRQadXQikn7RMBazM1ZS2l4_kW9qG-uj2VK-0obAwbuWXPjeqYOFLqd4k3wn2mtbNna9fNRa3gUTnWJkGTQJFp dZOmXS7cpQK-DZSQVk8uR54peP5Q&sig=AHIEtbSrxCPKwvXQSHN1cy3_pXimXu562w) tells me " Blue/Red Stripe - connect to brown (o2 sensor power wire)" so do I connect this blue/redstripe wire to the o2 power on the chassis side? because I thought I was suppose to connect the brown wire from the SR harness side with the other brown wire on the KA chassis side. I know this isn't rocket science but damn it there is something I am not getting here, somebody clue me in on where the o2 sensor on the harness side is suppose to be connected to? and the main ignition power wires
