Regulator Rectifier

Thank you!
Think I'll try out the dohc regulator. That's the cheapest and closest one to me right now. If it's possible to make any of these work with any model, then I'm sure my electrician can wire it up right when I take the bike to him.
I don't recall what connectors the DOHC reg/rec has. Might need rewiring to connect.
If he's good and understands the different type of regulators, then no problem.
Am I right: with the low-side switched like RR32 (dohc regulator) it should be connected like this (one wire from field coil to ground and one to regulator): https://i.imgur.com/xChoS34.jpg?2
And with high-side switch like the RR38 should be connected like this (both wires from field coil to regulator): https://www.xs400.com/attachments/xs400_1979_wiring_diagram-jpg.3854/
Yes, the important part to note on both is where the other field coil wire goes. On one it goes to the brown 12v line and regulator, on the other it goes to ground.
 
Hi. I got the regulator/rectifier today. But my electrician don't have time next few days, but I just can't wait. :D
I wanted to ask if I connect it wrong is it possible to mess the reg/rectifier up. Like if it's ground switching regulator and I connect it to positive or other way round, is it possible to mess it up? It should be ground switching (for xs400 dohc), but the shop is not 100% sure.
