I have a 96 civic with a y7 i am swapping to a b18b1 the problem I am running into is the wiring on the drivers side that goes to the fuse block under the dash. I was looking at a b20, and I noticed that that plug was the same. Is there any differences between those two harnesses?? If not, can I use the one out of the b20 if their is no difference? Any help would be appreciated. Thanks
