Audio Input Wiring ? 1954 Sears 4048 Radio Phono

The separate power supply is re-capped and functional.

Dave1138 did me a favor and checked the radio/phono
chassis, and said it has a good chance to work with a
re-cap. So, I'll do that later this month.

What I want to do is wire an RCA jack to the phono
input plug, so I can plug in a record changer, CD, et cetera.

I have the original 3 prong male phono plug, but the V-M
changer is missing.

Looking at the phono input diagram, I think one connection
probably went to the changer tonearm or base.

Would someone post their diagram of how to do the new wiring ?

Thanks !

RCA jack ground goes to bottom and right pins on the diagram. Signal (RCA plug center pin)goes to left pin.
