Help out with s14 harness and diff questions

[The5Connors]

I've searched and searched over and over again and can't find a definitive answer to either question I have.
First question is just clarification because my welded is gonna go soon after 6 years. But if I have two s13 open diffs, but one has 5 bolt axles and the other has 6 bolt. The half shafts should still be the same it's just the bolt pattern is different right?

And second question I pulled a full rb swap from my beat s13 hatch and have gotten it out into my s14 shell but obviously the engine harness doesn't plug into the fuse box or the dash. Can I just order a s14 dash connector for an s14 dash and and fusebox plugs then re pin it kinda like if I did a single slam to dual cam swap or do I need a whole new harness? Don't really wanna spend another 6-800 bucks if I don't have to for a car I'm just wanting to drive while I tear into my jz coupe.
I'm a s13 guy so all my stuff is s13. this is my first time touching an s14.

Any help would be awesome.

You can buy the s14 dash plug from wiring specialities

Nissan refers to it as the "Inner Joint" of the rear drive shaft. But yes, minus the bolt pattern they are the same. You can simply disassemble the shaft & swap them.
