So the pinout was the same, just different colored wires?

Congrats on getting it working!

I gotta learn how to do this kind of board work and also read electrical wiring diagrams in a much more detailed manner.
Wiring diagrams aren't too too hard to read, but in some places I think that I would get confused by exactly how much current is supposed to be going through some areas, and how much resistance other areas are supposed to have. Would also help to know how the components and switches are laid out.

It seems like a whole nother world of cheap mods (and mods in general) seem to open up with this kind of knowledge.

I don't think i'd want to MAKE computer boards, but working on them to do random stuff would be kinda fun.

Do you guys have any good resources to start with?
Particularly in automotive?

You can also buy them with this mod already done:

They also offer with RCA outs and BT:

Good write up OP, I'll give this a try on my tape deck model.

Ouch, for that price you can have a nice 2DIN navigation unit and the Metra kit.

Hello, I subscribed to this forum to thank AstroWill for this very nice tutorial.
I did the fix yesterday, and it works perfect : )
(It took me a bit of time to figure out the brown line needed to be connected to the ground, which is the metal part of the radio)

Anyway, thank you again very much!

I now have 9 jacks left over that I would happily give away as my give back to the community.
I live in Glendale CA, if you need one just send me a PM and come pick it up.

I was wanting to replace my 12v cigarette lighter with a panel mount USB/ 3.5aux jack.

I have the factory tape deck with remote CD.

I’d love a simple “plug and play” scenario. Anyone more handy with wiring than I am want to make a few bucks putting it together?

Using the cable that runs to the remote cd player makes it even easier. They also make units that go between there that you can purchase, does the same thing https://amzn.to/3imkFw1

Thank you! I’ve seen that part before.

That requires me to not only keep the CD player, but play a CD in it.

I was hoping for a 3.5 Aux jack that would replace the CD player, install in the 12v cigarette lighter outlet (with a usb) and put a storage pocket where the CD player was.

It seems like it should be doable unless I’m missing something??

The remote CD player has to be there if you are going to tie into the external wiring that runs to the head unit. It communicates with the head unit to let it know that there is a CD in the unit.

Another really nice clean option is to upgrade your head unit to a double DIN that already has the 3.5 aux/bluetooth/USB/Navigation or whatever options you choose. Metra makes a kit for it now.

This is the direction I ended up going.
