Wire harness fitment

[Element26]

I've had a hard time deciphering the differences between some of the older wiring harnesses. I have a 1981 XS400 that I'm rebuilding and have had a helluva hard time finding a new wiring harness (lack of time, not laziness, has been my foe). I've easily found harnesses for the 650's of that era and I'm wondering if I'd have any problem using one of those instead. Is there a gauge issue? Extra leads? Extra ohms? Please let me know which direction to go!!!

It's a different harness won't work. The 81-82 sohc xs400 harness is the only plug and play that will work. The 80 sohc will be close but don't have the extra safety relays as the later bikes.
