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!
