Wiring up my circa 1960sPanasonic transister radio

[mamoose124]

I am about to wire up the circa 1960s Panasonic transistor radio that was in my car when I dismantled it for painting. It wasn't working at the time so I don't know if it does work and I don't know how to test it to find out before installing it in the car. The radio was made by Matsushita Communications Industries of Japan and can be switched either + or - ground. However, looking at the wiring coming from the box stumps me. Instead of having one yellow full-time hot wire, one red "key-on" wire and a black ground wire, plus speaker wires, there are only thee wires emerging from my radio: one blue wire with half of a fuse holder attached. I assume this is the full-time hot wire that is normally yellow. Only two remaining wires emerge from the box: both are grey and I assume they are for wiring the two KRACO speakers under the dash at each side of the car. As far as grounding goes, I assume I can simply ground the radio case but I have no idea how to hook up the other three wires. I have googled my head off and can find no simple wiring diagrams that illustrate how to hook up this radio. Any suggestions will be greatly appreciated.

Think you are right with assumption that the blue one with fuse holder remains must be the hot wire. Grounding via chassis or antenna shield. If there are are only two other grey cables they must be the speaker connections. Would assume it's a Mono Radio then...

Mike,
The yellow wire that is common with today stereos is a constant power to keep the clock running when
power to the car is shut off. You are correct that the blue wire is the power wire and it is keyed on power.
The other two are speaker power and ground(for the speaker) as that's most likely not a stereo. You can split
them with wires running to the two speakers you have under the dash, but it still won't be stereo.

Hope that helps!
Cheers!
