Hello, I´m looking schematics and wiring diagrams for old Delco Car stereo.
I like to make aux input on this old stereo.
Looks:

Can anyone help?

Thanks

I doubt you'll be able to do much with it. Probably a tape adapter or RF modulator will be your only options.

You can't add AUX input to a stereo that doesn't have another input (like for a CD changer).
PSYKO_Inc is right. A casette adapter or FM modulator are your only options.

Thats not entirely accurate! Many many moon ago while working for a local stereo installation store I bugged the front office using a simular radio and a cheap mic connecting it to the tape head wires. I was shocked that it worked and that it worked well. Anything is possible but I can not vouch for sound quality but if your looking to try something like that I would start there. Good luck!

It's certainly possible.

You would need the schematics or a good scope (and maybe a signal injector/tracer) but you should be able to get there.

The internal tuner and tape player have low level signal at some point, just splice in there. You might need some EQ and impedance correction though...

An FM modulator is also a good option, as sound quality won't be your number one priority when using this radio.

Another option is emptying the radio and putting in some stuff to translate the buttons to USB. Then you could use a carpc with the HQCT-i and an amp or the HQCT-eA (when it's out)...

Good luck!

Thanks for ansvers, I know there is possible to do it 2 ways.

1. make it to the tape head or...

2. cut AM line, I dont need AM anyway and I´d like to make
it just there, then I can use the big button in front AM/FM

Sorry my bad english btw

I like to know can I find some schematics for this radio?

hey rokipeer, that is excactly what i am having done to my oem stock radio.. I own a kia sorento... And the stock delphi delco radio has no aux inputs.. I have friend in korea who is modifying it.. so it will use am as aux in... I am still debating the hcqt-i because if i use the eA model i will lose my factory radio controls... and yes i thought about the swi and the usb controller by a site member...
