Hey im swapping a 2jzge in a 93 s13. So im looking at my f1 plug and it looks like the same wire colors as the picture on this guide im following here.

but i noticed the color pinout on the picture below is different than my f1 plug. Did nissan just use whatever wire they had lying around or something? I just wired it up the way it looks in the picture but the f1 colors are definalty completely different. Im alittle scared to try to turn it on right now

Thanks a fellow drifter
