Alternator wiring harness - is JDM and USDM the same?

I've got a JDM and about to buy an USDM harness. The one that goes to the alternator/coils/fuse box. Are they the same?

Since no one has replied, I'm pretty sure they would both be the same, or easily modified, if not exactly the same, because they connect to everything on the spark plug side of the block from the battery back to the starter, on both versions,
unlike the JDM emissions harness vs USDM version, which are quite different in many respects.

I would ask the seller for better harness connector pics ? or find out from a Japan distributor if the harness part # is the same as the USDM one ?

I'm 99% sure they are the same. I rebuilt a starting/charging harness YEARS ago for my car and I'm pretty sure I got it from a JDM long block that I had bought.

More I think about it the more I'm certain they are identical.
