InPhase IPX-FD1 Stereo


Recommended Posts

Hi all,

I recently got given an Inphase IPX-FD1 car stereo system but it was missing the power connector lead and wiring loom to connect to ISO/Ford Stereo wiring.

Has anyone out there either got this stereo or got a CORRECT wiring diagram for the 20 pin connector that goes into the back of the stereo please? I have the plug itself but the wiring is obviously not right as the only ground pin that matches up correctly to a ground connector pin in the stereo (as tested by continuity from wire to stereo chassis) is the one on the far side on its own.

The plug is laid out in 2 rows of 9 pins with a wider outer pin at either end.

Like this:


|          2.    3.   4.   5.   6.   7.   8.   9.   10.                |

| 1 ---                                                                ---11    |

|          12. 13. 14. 15. 16. 17. 18. 19. 20.               |


For the sake or argument, I have labelled the pins accordingly

Pin 11 is a ground

Pin 6 is a ground

Pin 18 is a ground

The rest I have no idea but the plug I bought only has 1 ground wire that matches up with the relevant pin - pin 11.


I would either like to find a photo of an original power connector or a wiring diagram that shows which wire fits where into the plug so I can get the stereo connected up (note, the stereo was given to me by an old friend who has his car scrapped and he didn't take the power wire out of the car).

Does nobody have any ideas on this?

Is there a way to use a multimeter to test the pins and work out what each one is based on resistance or something?
