[Kenwood] TS450S and SGC ADSP2 speaker

[Kathy & Jürgen]

I have just ordered a SG7014 mobile speaker for my TS450S. I left my manual
at an other QTH.   Can someone with a manual please  tell me how to hook up
the 12V for the speaker. Is switched 12VDC  available at the rear of the
radio? What plug is required and which pins?.
I could go and take the radio out of the van  and figure it out but it's
+15F outside and I hope to find out what I need from here in the warm shack.
                                                                      TIA
