Radio pin out

Hi All - I just swapped out my stock radio, with cassette and CD. Put in a new head unit with Bluetooth for music and hands free phone, etc. I just discovered I left a CD in the old radio :-( - and there is no way I want to pull the new unit to get at the harnesses and plug the old radio to power it up and rescue the CD - if I don't have to. Can anyone tell me which pin is the power in? I've searched online and haven't found one that looks like mine. I don't want to just start poking around with 12v and risk frying the radio. The radio still works great - just no Bluetooth.
I've attached photo to show my radio's plug config.

Since certain electronics/pin outs change on our 1st Gen, what year/model/trim do you have ?
That is going to be awful close when applying 12v so closely to other pins. Might want to reconsider temporarily hooking it back up....IMHO !

While it may not be same as your MY, my JBL system with RSES, connector R14 are pin 10 and 11....gnd/12v respectfully ! Yours may be different according to what year

 

Thanks - I have the access cab and it's not a JBL - I believe pin #20 is the main 12v in, on my Fujitsu Ten/Toyota radio. The pin above is a ground so if I hit it, it may spark, but shouldn't fry any thing. Pulling the radio is not a huge job, but will do that if my try to "hot wire" the radio on the bench fails.
Thanks again for the quick response!

 

What year.....with that, one can look at electrical drawings we have available on this site to find proper pinouts !

 

sorry - had to go run errands. 2003, I'll try a search. Thanks again.
