Pioneer DEH-225 Car Audio

Hello, I am trying to hook this unit up in my 91 Cadallic Deville. I have everything wired up other than my power antenna. There is a blue wire comming from the unit labeled system remote control. Do you know what this is for and do you have any idea how I can hook up my antenna? Thanks

DO NOT connect your antenna to the RED wire! The Blue/Remote wire is used for Power antenna's and or Amps. If you are hooking up more than 1 amp you need to use a relay to trigger your amps otherwise you might overload your head unit.

Re: Pioneer DEH-225 Car Audio

The system remote control is usually a blue wire on your decks harness and it is for an amplifier for a sub or other speakers. It sends power to the subs amp when the deck is turned on. You may need to find the wires coming off the antenna and splice them into the red power switching wire 12v on you decks wire harness. Good luck

I need wiring diagram for pioneer deh p56

Pioneer follows the universal after-market color code, so if your CD player was made in the last ten years or so, the wires should go like this: Yellow: Constant +12VDC (memory) Red: key-switched +12VDC (accessory) Black: Ground Blue/white: amp remote or power antenna output Speaker wires: The solid-color wire of each pair is positive; the black-striped wire is negative. Left front: white Right front: gray Left rear: green Right rear: violet

Dont know the wiring diagram

Positvie is red, ground is black, and or black with a white stripe. the yellow wire is also a positive wire, it is the memory wire which should be hooked to something that will always be hot, even when the key is completely off. If you have a power antenna, that is controlled by the blue wire

Wiring Pioneer DEH-225 to 1996 Kia Sportage

the difference between constant and switched 12V is the constant is usually for the clock and memory. it draws precious little current. the switched would be for the radio and amp once the car is turned on. You can use tape but either a wire nut (not the pink ones) or a crimp on cap would be better than using tape.

No AM!


A possibility is that the antenna cable/plug is shorted. You can try verifying this with a continuity tester or simply unplug the antenna and stick a piece of insulated wire with the tip/end stripped into the antenna. Try the AM with the wire as the antenna. Just be carefully not go that far as the wire may reach the PCB/electronics.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
