Ok I looked at the write up and I got a question about it. I have a 1992 civic LX 4dr. I am putting a Z6 motor in it, as I was reading I noticed at the bottom it says that if you use the Si/Ex engine wiring harness it is PnP. What if I don't use it? I can always go to the junkyard and hope to get it, but I dunno what all I would need to get out of the junkyard car. Just a question incase I try to install it and have some problems. Thanks!
