Hi, if the connector is still there, it is easiest to purchase a ford wiring adapter. The adapter will match the factory wires to an aftermarket stereo. If the connector is gone, see your factory wire colors below. Please let me know if you need additional help or have any questions, and thanks for using FixYa.
1996 Ford Escort Car Stereo Wiring Diagram
Car Radio Battery Constant 12v+ Wire: Blue/Red
Car Radio Accessory Switched 12v+ Wire: Blue/Black
Car Radio Ground Wire: Black
Car Radio Illumination Wire: Red/Black
Left Front Speaker Positive Wire (+): Violet
Left Front Speaker Negative Wire (-): Blue/Orange
Right Front Speaker Positive Wire (+): Blue/White
Right Front Speaker Negative Wire (-): White
Left Rear Speaker Positive Wire (+): White/Blue
Left Rear Speaker Negative Wire (-): Red/Blue
Right Rear Speaker Positive Wire (+): White/Green
Right Rear Speaker Negative Wire (-): Blue

The main colors are:

Green - L+
White - L -
Brown - R+
Gray - R-

There are 3 sets of these. The ones with thinner wire are for high level input (from a stereo's speaker outputs). The two other thick sets are the speaker outputs to front and rear. They should've been attached to connectors labeled front and rear, if they aren't, you gotta find out through trial and error with the fader. Lastly, black is for ground of course, then the thin red wire is for 12V+ power (on with ignition), and the thicker red wire is power output to a deck, if you want it to turn on along with the amp/eq.

It is best to buy a connector pigtail for Ford, but you can wire directly using the below color code for the factory wiring. use the color code from the pioneer to match to the factory wires. If you have more questions, please reply.

You need 1 thick ground cable ( usually brown)
you need 1 thick power cable ( same thickness and wire as ground usually red )
you should have 1 rem wire ( thin blue )
RCAs, 2 for sub, extra 2 for 2 speakers.
The rest I have no idea what they are.

You need speaker cables to sub or amp.

Some products use different colouring. Maybe the 9 pin connector is for head deck to speakers.
