aFepower.com Page 6
Disconnect both batteries and locate the ECM Connector under the hood on the

wiring harness plug. Inside the truck remove the 2 bolts (7mm socket) holding the ECM
in place. Remove the ECM from the truck.

Stock ECM J3 Port Preparation
aFepower.com Page 7
Once you have the ECM removed, on the opposite end of the wiring harness plug is a
small plastic or metal cover. Remove this cover gently. Inside this J3 port is a circuit
board with double-sided contacts that must be cleaned of conformal coating. J3 Port
contacts must be cleaned thoroughly, or the chip will not make proper contact with the
ECM.
Scrub off the coating using the Scotch-Brite pad provided or a fine sandpaper. The
contacts should start to become shiny and metallic copper color. Scrub only until you
begin to see a hint of copper. Wipe off any remaining coating with rubbing alcohol or
lacquer thinner on a paper towel.
Please verify that BOTH sides of the edge connector were cleaned thoroughly.
Improper cleaning is the most common reason for chip failure or incorrect operation.

Installing the Switch/Chip

The proper orientation of the chip is with the circuit board of the chip and the switch
cable on the larger side of the J3 port opening.

Re-Installing the ECM
aFepower.com Page 9
Once you have properly mounted the chip, secure the chip to the ECM with a piece of
package sealing or Duct tape.
Be sure the box holding the computer in place does not bind the chip causing it to tilt
and lose connection. Return the ECM to its location and re-connect the wiring harness
and 2 bolts in box. Reconnect Batteries.
Install switch and sticker in a convenient location. Your installation is now complete.
