6600 Series Chip Module Installation
The vehicle must be turned off and the keys MUST NOT be in the ignition during the entire installation. We recommend that you place the keys in your pocket while installing the module. Failure to follow this suggestion may result in damage to your PCM.
Removal of PCM
Begin by disconnecting the negative battery terminal of your car’s battery. Next, locate your car’s PCM. The PCM is held in place by a 7/32” or 5.5mm bolt. Please remove this bolt. Next, remove the wiring harness by use of 10mm socket and ratchet. Slowly and gently pull the PCM out of its location and out of the car.
PCM cleaning and preparation
1. Once you have removed the PCM, take a look at the side of the PCM opposite from the wiring harness. Gently, pry off the plastic or metal cover. The J3 port (chip port) will now be exposed. See figure 1.
2. Next, to properly clean the J3 connector, remove both covers from the PCM. To do this, remove the 5.5mm hex screws on the side of the PCM. See figure 2.
3. On older models, use a clean rag to wipe away the protective grease on either side of the connector. On newer models there is no grease, but instead there is rubber coating on the connector. Use a piece of Scotchbrite to scrub away the rubber coating on the port. On all models, then use a piece of Scotchbrite to sand the contacts until hint of copper can be seen evenly on both sides. DO NOT go past the copper or you will ruin the PCM.
It is extremely important that the port is properly cleaned. Otherwise, the car may not start or the chip may not function properly. Do not use sandpaper or anything other than what we recommend. Failure to follow these instructions may result in damage to your PCM. See figure 3 and 4.
4. Reinstall the cover on the computer and hand tighten the hex bolts.
Installing the module
1. Slide the switch cable connector onto the slot in the chip. See figure 5.
2. Insert the module into the J3 port as shown. See figure 6 for correct mounting.
3. Carefully work the PCM to its original location.
4. Route the switch to wherever you will want to mount it or place it.
5. Reconnect the negative battery terminal.
