Hello,

I have a 2001 Chevrolet Prizm LSi (essentially a Toyota Corolla in downgraded
interior trim) with the factory AM/FM/CD stereo. It looks like there was an
AM/FM/CD/Cass. option also, as there is a big empty space in the bottom of the
radio and an opening in the front of the metal radio chassis behind the
plastic faceplate.

I need the pinout of the rear connector on the radio. The connector is
rectangular with 24 round pins in two rows of 12, top row being labeled "A"
1-12 and bottom row "B" 1-12. Using various sources I have about half the
pins and wire colors identified but haven't found the functions I want. I'd
like to add ability to switch to an external audio source if possible - I
think with all those unused pins, it's got to be there somewhere!

Late model Saturns appear to use the same connector but I don't know if the
pinout matches.

I prefer email replies but will check here too. See below to email me.

TIA

In case this is any help, the radio is Delco part number 30024333, made

Hows your program writing ability, its most likely done
with data info.
And even the Saturn 24 pin are not all the same.

Well, I know 11 of the pins for sure (ground, constant +12V, ACC/IGN switched
+12V, and 8 for speakers) plus 3 more that I'm fairly sure are lights (+12V),
lights (on dimmer), and switched output for either power antenna or amp. I
think it's likely that similar models of this HU have built-in CD changer
control which would use some of the remaining 10, and would definitely need
line-in which would probably use 4 more. Some (most or all?) models may also
have line-out for use with an external amp (which I may want to use in the
near future too.) If the changer control is a serial protocol it could
possibly only use 1 or 2 pins, which with line in/out would fill the connector
nicely.
