Alright I'm redoing some of the wiring on my car and I noticed something involving the o2 sensor (brown wiring on main harness plugs), according to HT it just says "wire the brown wire to an 12v ss" when checking my harness I realized I have 2 brown wires, one comes off the tan connector on the KA24DE harness, while the other comes off the big grey harness on the CA18DET harness. My question is, which one should I wire up? Should I just splice them both together and wire them to the 12v ss? Here's some pictures to help.

^Brown wire on big grey CA18 plug

So which one should I wire up? Should I splice them both? Help me out guys, I want my beast on the road, I'm driving a beater CRX and it's making me queezy every time I get in it, I need my Nissan!

On my ka brown plug I had 2 brown wires side by side. I wired up my 02 sensor wire from the ca harness to the outer brown wire on the ka side, works like a charm.



hopes this helps,

Did you just wire them right into eachother? Or did you splice them together then run them into a 12v source?

Just wire the brown wire on the brown KA plug (if there are 2 brown wires use the outer one) to the brown wire coming out of the harness that was originally connected to the grey CA plug. Kinda hard to explain but its very simple.
