Engine swap harness question?

[Gearhead4G63]

In looking to drop in a 6 bolt 4g63 into my GS spyder 4g64. Do they use the same wire harness? The ecu looks the same on the 4g63 as the 4g64, I have both but do I need to swap the harness and ecu as well?

I just did my 6bolt swap on my gs spyder.I ended up using a 95 ecu and harness every thing hooked up just fine. but the gs spyder wire harness will also work you just needs a knock sensor wire and the injector suppersser (not sure what it's called) and an ecu. I changed mine because of a bad harness from a small fire
