ok the real question here when you drop in your motor what engine harness did you use? by the sound of it you used the HF engine harness. you should have gotten the z6(D16z6) harness. i understand the rywire harness how it helps w/the ecu/distrubiter jumping from ODB0 to ODB1. but there are other easier ways in the converstion. if/and you're changing your engine the engine harness is a start. second the rywire ecu jumper helps also. then to avoid headaches w/the dizzy here is a chart that can help you:
with this you can rewire/resolder and coverted the dizzy so use the HF plug. so in turn all you doing is cutting the wires from the 4th gen to make a 5th gen work.
i hope i made some sense. i jump around but i hope i made sense. a while back i spoke w/Rywire on asking them to make me a custom engine harness which took a 4th gen and a 5th gen engine harness and make one. the price was $350 or $375 i can't remember. i still going to do it it's just i've been busy.
