sup guys... first swap in a vx and i basically need to know how i am supposed to wire up the O2.... i am using 95 gsr harness so would it be all plug and play or is there more to it?

i had a similar problemwith my b16 in my vx, i got frustered and i just wired it directly to the ecu and bypassed the plug.

if u are dropping in a b18c1 into a 902-95 civic no matter which one it is and you use the gsr engine harness all youhave to do is plug up the engin harness to the civic shock tower harness. you dont have to rewire any o2 sensor unless your motor didnt come with teh 4 wire o2 sensor. now you still will have to wire up vtec wires from the ecu to the motor just be creative.

Well, I cut a couple hours out of my evening to answer this bad boy, then I find out you're using a GS-R harness.

GS-R harness is plug and play.

If you're going to use a VX harness, and modify it for the 02 sensor (I can show you how to do the knock sensor too), here's what you do.

Remember that the stock 02 sensor on the VX is in the top of the manifold. The plug which plugged into it is an 8 pin connector. Here's a detailed diagram, and real-life pics which show where to cut and where to splice. You'll need 4 butt connectors, 4 feet of 4 different colored wires (what you use is up to you, I used green, orange, white, and yellow), and a 4 wire O2 plug connector with pins on the ends of the new wires.

Welp, look at the diagram that I made in paint (haha), and the pics, and it should explain itself.
