just got a few question about a swap that I'm about to do, I have a 93 civic dx and I'm putting in a B16a JDM..... I got a good deal on a motor but the thing is, it didnt came with a wiring harness. so my question is, can i used my stock wiring harnes from the d15b7? cause i'm looking at my b16a and it has three o2 sensor while the d15b7 has one with four wires attach to it.... can any one please help me with this.
