I just discovered another quick tip for those of you who are using the K24 intake manifold and fuel rail like I am with the EP3 harness. The plastic cover over the fuel injector wiring on the EP3 harness doesn't clip onto the K24's fuel rail, so I took the cover off of the cut K24 harness and put it on the EP3 harness. It's easy to swap, it just clips on. This isn't necessary, but I personally prefer this setup as it looks cleaner and more OEM instead of looking like I put the wrong harness on the engine. Also, having wiring properly fastened down where possible reduces the chances of damaged wiring or rattles.
