Hey guys, I was just wondering if Im able to use my d16z6 engine harness for my b16a2 swap into my 93 civic ex. I've been doing some research and I found out that i'd have to wire in a secondary O2 sensor. Just needed some more clarification. Thanks in advance,

Yes you can use your old harness. You will have to add a knock sensor wire directly to ecu harness plugs. You will have to extend a few plugs and make sure to label the iacv, iat, and tps sensors plugs. Making sure not to mis-plug as it will burn something up in the ecu. No second o2 sensor is needed because you are obd1. You can reuse your ecu as long as it is chipped for a b16a, therefore saving you time by not needing a second o2 sensor and obd2 cat converter. Very simple and straight forward swap. good luck
