1980 400 XS.  I have a seperate five wire regulator and three wire rectifier.  If I want to replace both with one unit do I just wire the old rectifier (three white, one black, one red), to new combo unit and then old regulator, ( black, green and brown), to the new unit?

So I am just rewiring two units into one.  Thanks for reading.

There are  only two wires for the regulator on the new combo unit, the old one has three.  Do I ground the green and splice the bnlack and brown?
