Soooooo.. I was going off the teg's engine harness with the civic's DX harness and I ran into this. I spliced into this plug as it was in the teg's but for the other cable which came off a plug with 3 cables, which I can't find in the civic's harness, I don't know what to do with. I'm guessing it's the vtec plug's ground wire?... should I just delete it or what should I splice into or add? It's the one labeled "wtf"
