quick SR wiring harness question (already searched)

[Milly]

Okay so i searched and didn't come up with anything...

Well anyways i fixed my sr harness and modified it with the ka plugs etc..

well i was on the last step and the "main power plugs" that hook up near stock battery location i got confused..

Theres a brown wire in the sr harness and it said it's the o2 sensor power.

Do i just add an extension to that brown wire and run it to a 12v source? like the ignition?

Thanks!

You can for sure, ITs the heater wire that turns on the 02 sensor. so make sure it is on ign only circuit.

Okay so that single brown wire is the correct one? I just wasn't sure if i had the right one
