I already have this engine prepped and ready to drop in and I know all of the rewiring I'm supposed to do, but do I have to do it since this engine already came out of an accord. I have another swapped accord that had to have the rewiring done on it, but it is subtly different in it's setup because it came out of prelude. Intake manifold is different, drivers side mount is different and several other little things. I don't want to do all that work on the harness if I don't have to? Anyone have experience with this? Thanks.
