Generic Ford Instructions
A. Removing the Computer:
1. The first step is to locate and remove the vehicle's computer (Figure 1). The most popular places that the computer will be either on the driver side firewall, passenger side firewall, behind the glove box, or behind the passenger side kick panel. The first step in removing the computer is to disconnect the wiring harness from the computer. There will be a 10mm bolt in the middle of the harness. Loosen bolt to disconnect harness (Figure 2).

2. Pull the computer straight out from its location. Note which way the computer comes out so you can replace the computer the same way it comes out.
B. Connector Preparation:
1. Once you have the computer removed, locate the end opposite of the wiring harness connector. This end usually has either a small black plastic cover or a thin metal cover. Pry the cover out gently. A double-sided electrical edge will now be exposed (Figure 4).

2. Most electrical connectors have a thin coating of protective grease on them (Figure 5). Remove this using a Q-tip, cloth, or paper towel. Make sure you clean both sides of the connector thoroughly, you can use a small amount of alcohol if necessary. Also, most edge connectors have a thin lacquer or coating over the electrical contacts. This is from the factory and is normal. To clean this, use a sharp knife or a flat screwdriver. Be careful to apply gentle pressure and clean only this coating off, do not remove or damage the electrical contacts. We recommend cleaning one contact at a time, to minimize problems or damage. Clean the area in between the contacts also. (Remember to clean both sides of the electrical connector.) If you start to see the silver contacts give off fine metal shavings, you are done. STOP!

3. Control Device installation. Your control device may be in the form of either a "chip" or a small "printed circuit board". Use the appropriate instructions below, in other words, either 3.A or 3.B below.
3A. Chip Installation. You can now plug the chip into the connector. The chip will fit flush with the computer box (Figure 6a). We recommend securing the chip with electrical tape or duct tape to the computer box (Figure 6b).

3B. P.C. Board Installation. Bend the flat cable (between the board's connector and the board) in a "U" shape. The board will slip into the computer box so that it is not exposed to dust and dirt. You can now carefully press the female board connector onto the computer's exposed male connector. We recommend covering the opening with the original cover or electrical tape or duct tape (Figure 7).

C. Re-installing Computer:
1. Replace the computer the same way it came out.
2. Re-connect the wire harness and tighten the 10mm bolt in the center of the wiring harness. Test the vehicle by starting the vehicle and checking for a "check engine soon" light. If the engine starts properly, CONGRATULATIONS, YOU ARE DONE!
