Hey im looking for a Adapter to Put my new Radio in my car. The blue one is where i dont find a Adapter For. The Adapter I bought fits in the Radio but Not in the car cables. So i need one that has Connection between this 2 types

Looks like your adapter is right, follow the blue connector
phungki@reddit
Brand and model of car? Is the blue connector a factory harness plug?

Did you buy it used? If you bought it used that would explain why it’s not plugging into your cars wiring, because it likely has plugs on it for a different car.
Typically you need two things to install a headunit into a car.
1 and 2 are then soldered together to create a patch harness where one side plugs into the headunit and the other side plugs into the car.

The car or the Radio ?:D i bought the car used the Radio IS a cheap 20 Euro Amazon Radio. I think the cables are already new ones someone installed before i Had the car maybe even another cheap Radio with the right Slot for this cable would be fine as Long as I dont have to do some Tricky Wiring and Just have to Plug IT in

Guess: The factory radio and amplifiers were separate but the aftermarket head unit that you’re replacing has an integrated amplifier. The previous owner would have had to bypass the factory amplifiers. Different brand of car but this is something that I’ve had to deal with. To see if this is accurate I’d look up whether the car was built with separate amplifiers, locate them, then check to see if they’ve been removed or bypassed.

It’s not clear what you are working with. The car had a factory radio in it or an aftermarket one? The radio was used or brand new? The wiring you have, did it come with the radio or was it in the car already? More pictures of everything is needed.

I Put more Photos in a thread on my Profile maybe that helps
phungki@reddit
Okay that helps. In your second photo it looks like if you continue pulling the wiring further out of the dash you’ll hit another set of plugs. I think this is your issue, pull the wiring further out and unplug the harness that is plugged into your car already. You should then be able to plug your new harness in. More photos of the current wiring in the car would help.

I have more Photos now do i need to make a new Post to Show them ?

Are there still the old school wiring harnesses that require you to match up wires and butt splice them together, or is everything mostly plug and play?
doubled112@reddit
The last radio install I did was like that, it wasn't that lon-oh no! That was 10 years ago now.
darthlame@reddit
You might be old school, I’m not sure. I know the last radio install I did was around 2005, and I didn’t have to to any splicing. That was pretty straight forward with adapter harness. The previous one I did in 1998 I had to do splices
phungki@reddit
Those don’t look like factory Toyota plugs. Can you take more picture of the wiring? Pull that wiring out further and check if there are other plugs behind those ones.

Read your other replies. If the blue one is not original, then just cut it off and attach the wires from the radio’s harness. Make sure you figure out which wire is which before hand of course and note it all down.
You can usually figure out by the colors:
Red = accessories wire (this usually powers up the lights on the radio) Yellow = constant power Blue = switched power (on when you turn your key to ACC) Black = Ground
The rest should be speakers that comes in pairs. For example white and White with a stripe, gray and gray with a stripe. The stripe cable is usually the negative terminal on the speaker.
Of course, these may not be 100% set in stone but from the hand full of aftermarket radios I’ve installed, it’s usually correct. Check with a multimeter to be sure.

As others have said the blue one looks like a pioneer radio plug.
You need to follow the wires to see if it's plugged to the original car wiring harness or if the previous owner cut and spliced it to install the radio.
If the blue connector wires end with another connector or two you should be able to use the adapter you have to connect the radio. If the previous owner cut the wires you will have to find which wire does what on the car's workshop manual and crimp it to the corresponding wire of the adapter you bought.
I hope I explained myself in a simple way since you are clearly having a hard time figuring this out.
ZeRussian@reddit
Aight so the blue plug is proprietary pioneer plug, you won’t find a harness to go from that to your new radio. You will need to pull lightly on the blue plug and follow the wires that should lead you to 2 plugs that will match up to the 2 white plugs from your new harness. You will also need to remove and replace the metal cage that was securing pioneer radio because it won’t work for the new radio.
Side note, no idea what radio you bought, but radios that used to use the plugs from your new radio were junk.

Former car audio installer here. Your pictures don’t tell me enough.
Please explain in detail what the black, red and blue plugs came from or what they are connected to and I can help you.
From what I can tell, the blue plug is an aftermarket harness. Does it plug into the car harness or did someone cut the car harness and wire the aftermarket harness with the blue plug into it?
DM me pictures. If you can take good pics of both the red and black plug harnesses, blue harness and how it is connected to your car I can help you.
I need to see everything that you have, not just the plugs.

Thats the one i bought didnt Work i think the blue one is already one that issnt original from the car
wyvernpiss@reddit
Crutchfield usually has those type of things. Just put your car in and pretend you are buying a radio and it should pop up with all the adapters and harnesses for your car
kameronk92@reddit
or call them, they're all super helpful
PiratenPower@reddit
If you don't find one, you're gonna need to crimp that shit.
xampl9@reddit
FYI do not use 3M Scotchlok or similar insulation displacement crimps. They don’t last, and troubleshooting a loose connection from one is a nightmare.
