Alternator swap, connect field wire to itself?

The plug will be different on the newer style VR, but the wires are the same color, and you can pirate a plug end from any junkyard car with electronic ignition and splice it right in!

Looks like you bought the same alternator, single field roundback!!
Is it this one? More Information for STANDARD MOTOR PRODUCTS VR125T

Do you happen to know what kind of cars in the junkyard might have this connection? thanks bro
