2 wire regulator with 3 wire alternator?

I’ve been having a few electrical & starting issues recently, finally pin- pointed as a fried regulator/ rectifier. I have sourced a mosfed type from eBay, but it’s taking a while to turn up. In the meantime I have ‘borrowed’ the one from my 900ss ‘project’ (where project means in bits in the garage & has been for 2 years).
The one off the 900 has only 2 wires, whilst the S4R has a three wire alternator. My question is will I be doing any damage running the bike using this set up, I am seeing 14.3V at the battery with the engine running
