I'm having a little trouble finding plugs on my TII harness. I've look'd and my o2 sensor plug isn't there along with my temp sensor plug. I'm just gonna run new wires for these, for the o2 sensor, do I run a line to the green/yellow wire on the big yellow plug that connects to the ecu? I've look at wiring diagrams but I want to make sure that I get the right wire before I go hooking it up and starting my new install. I'm just gonna run my stock jdm downpipe with 31/2ft. of 2.5in straight pipe, no muffler. I'm anxious to get it started but don't have the money to buy a turbo-back right now.
