I wish to change the factory double din radio cassette audio unit in my 98 Mondeo to an aftermarket single din height CD/MP3/AM/FM audio unit. Which is the best wiring harness adaptor to use to go from Ford wiring to aftermarket unit?

Here's a couple of photos of the connectors:

Hmm... your connectors are different than ours! I'll search Google for our connector kits...

In non-premium sound, we have two 8 wire connectors, 1 black for speakers, and 1 gray for the power/antenna/etc.



Here's what the non-premium Cassette looks like:



--------------------

Early premium sound (like mine) has the same gray 8 pin power connector, but for speakers has this square black connector with 8? pins:



Can't find a decent pic of the rear, but this is what the early premium looks like:



Apparantly the later premium sound have a single connector similar to this:



With premium sound, the factory amp also has to be bypassed, otherwise it'll sound like s**t since it's not expecting the high level inputs from the new head unit!

Here's a pic of the premium sound CD player:



And the premium sound Cassette (not sure if any Contours had this, but anyway):



--------------------

Now on yours... The connectors pictured are TOTALLY different than ours. I wouldn't risk getting info from us since you may even have different colored wires... I do see that you have 18 possible wires, while we have 16.



I would suggest MEG, since they also have the double DIN radios and stuff.

Sorry dude!
