I am having a heck of a time finding the right wire harness for my car.  I have a 2003 Ford Focus ZX5 with the 6 disc in dash cd changer.  I have purchased several harnesses and none have fit this car.  I am including a picture of the plugs on the back of the radio in hopes someone knows what this needs.  Thank you everyone.

I actually bought those but the tabs that come off the stock plugs don't fit.  Do I need to remove them?

Shouldn't, I've used the UK version (looks the same of course) literally
100s of times over the last 20 years.
They are all made by, Amp/Tycho, Molex or Kramm.

The Metra picture again at first glance looks like the reverse or female, i.e. the car side.
OK, think I have the answer, just played with both ends from my bits box and they fitted together fine.
I have one end probably from a Bluetooth kit adaptor that looks suspiciously like your photo and I just plugged the standard head unit adaptors in with no problems.
Meanwhile there were two power plugs but they looked similar, 7 0f 9 (Star Trek?) and 8 of 9 pins fitted the later version had 2 grounds.
For your interest these are the pin-outs going left to right starting with the top, black power plug:-
Antenna rem +
Gnd.
Mute???
Illumination
ACC
Gnd.
12V+ constant.
Lower yellow speaker plug:-
Front left +
Ditto -
Rear left +
Ditto -
Front right +
Ditto -
Rear right +
ditto -.
If you PM me with your email address I'll send you the photos.

Hope this explains why I am having an issue.

I did some digging and found that the part I got is part number FD5940, I checked into the 70-1770
 and found it also has a part number of FD5000, So I am thinking I got the wrong harness.  Thanks everyone for your help

I think the only difference is that one has two grounds and the other one. It makes no difference.

The loom shown is a Japanese car radio to Euro ISO plugs for an aftermarket car radio, it certainly isn't OEM especially with that Scotchlok on it.
Most of the connectors are made by AMP-Tycho, Molex or Lucas.
