definitly choose to wire the dx one if your lazy enough go to hasport or rywire for a cross bred harness but it is pretty simple i did one it was the last thing i probably worried about, since the IM bracket on that to the block was anoying as hell to get off, just get a helms manual and info what you need off the tips off the internet (not the wiring since different sources count pins differently, plus thats what the helms is for)

oh yea also take your time read the diagrams twice solder once

dontcha hate that about ef's, the dpfi thing only civic si hatch, civic ex sedan (rare!), crx hf, and crx si's are mpfi and the rest are just over glorified carb's
