Remove the kick panel on the passenger side and take a look

What would I be looking for?

A metal box that is your computer. And if there is a chip in it I would guess it will have some sort of a logo on it other than Ford.

Nope, that's the way...

So, you can remove your kickpanel - it is held on by either one screw or one of those plastic push-pin things. If you have a '94+, you have to remove the door sill, but it just pulls up (no screws).

If you're going to take out the computer to look at it, I'd recommend that you disconnect your battery first...

Once the kickpanel is out, look for a metal box, about the size of a radio headunit. It's on end, with a HUGE connector connected to the bottom. You need to remove a couple small screws that hold a white plastic cage to the car, and remove a bolt that holds the huge connector to the bottom of the unit (this bolt is in the middle of the connector, facing down).

Now, you should be able to lower the computer down and out of it's cage. On the end that was facing upward, there's a service opening in the metal box. It has an 'edge connector', where the circuit board sticks out to the edge, and you can see the gold connectors. Looks kind of like a PC board from a very old computer. About 3" wide. If you DO have a chip, it is connected to that connector. If you HAD a chip, there will be scrape marks on that connector and the gooey coating will have been removed to make sure the chip had a good contact.

Just like Chiltons says - installation is the reverse of disassembly.

Good luck!
