IMPORTANT PLEASE READ CAREFULLY: – RISK OF AIR BAG DEPLOYMENT –

The installation of the PRO Module NEVER requires to work on AIR-BAG wires, but it might require to work close to them. 
Before proceeding with these installation instructions, unplug the battery of your car and wait 20 minutes, with the battery unplugged, for any stored energy to be discharged. 

Leave the battery disconnected during the entire installation until it’s all installed, ready to be tested. Even with the battery disconnected, always make sure the wires you are working on are the correct ones. Never work on AIR-BAG wires with a tester, voltmeter or light or any other instrument that has a battery.

How to reach the CCM and install the NEWROCKIES PassKEY 2 Bypass

The CCM is the module that manages the security and can be found under the center portion of the dash.

  1. Remove the negative Battery Cable.
  2. Remove the knee bolster on the left and the inner bracket.
  3. Unclip the radio speaker Amp and fuel pump relay.
  4. Slide the CCM out to get at the connectors to make the connections.

If the enclosure of your NEWROCKIES PRO Module is green and blue, please setup the switches as following (if enclosure is black, please submit a request to our support team for correct switch configurations):

Open the NEWROCKIES PRO Module’s cover (this will NOT void the warranty) by removing the 2 screws on the bottom. Inside there are 2 sets of switches.

Set the switches as in the photo here below:

PassKEY 2

Connect as following:

PRO Module
CAR Wires
RED
Splice with CCM connector C2, pin E5 (WHT/BLK or PNK) (NOTE: C2 connector sometimes can be white instead of green, but the wiring pin/colors should match. Sometimes the rows are called c,d instead of e,f so this pin would be C5 instead of E5)
WHT
Not Used
BLK
Splice with CCM connector C1 pin C1 (BLK/WHT)
PPL
Splice with CCM connector C2 pin F4 (Black/yellow or yellow/black) (NOTE: C2 connector sometimes can be white instead of green, but the wiring pin/colors should match. Sometimes the rows are called c,d instead of e,f so this pin would be D4 instead of F4)
GRN
Cut wire on CCM connector C1 pin D3 (DK BLUE) and connect it to GRN of the bypass (toward the harness)
YEL
Not Used
BRN
Not Used
NOTE: The CCM must be plugged back in after installation.

IMPORTANT NOTE:

We have found several cases of these Corvette years that either have different plugs colors at the CCM or wire color/pin don’t match the instructions. Those cases seem to have remained largely undocumented. If this is your case, there is another installation option available at the ECM.

The ECM in those Corvette can be found under the hood near the battery.

1990-1991 Chevy Corvette ECM Location

Locate it, and then you do this alternative connection:

  1. On the red ECM connector, cut the the dark blue on terminal 6 and connect the GRN of the PRO Module to the side of the wire that goes toward the connector.
  2. Splice the RED of the PRO Module to terminal 10 pink/black of the ECM Connector.
  3. Ground the BLK of the PRO Module to a metal chassy ground.

Plug the connector back into the ECM

Troubleshooting

  1. Make sure connector’s pinout and wiring colors of your car are both matching exactly those of our instructions. If not, please Submit a Request to our support team with details of the pinout and wiring colors in your car.
  2. Is the light on the side of the PRO module turning on? If not check power between RED and BLK wires of the PRO module installed and with the key in the ON position (you can use a power-meter or a light) and Submit a Request to our support team with results of the measurement.​
  3. If your instructions do NOT make use of the PPL wire of the PRO Module then skip this step, otherwise, if you use the PPL wire and points (1) and (2) above are correct and your car is not even cranking then make sure the PPL wire of the PRO bypass is connected correctly and the connection is tight. Also try shorting with a loose piece of wire the PPL and BLK of the PRO module.  
  4. If car is still not cranking then Submit a Request to our technical support team detailing the tests you have done and the results.
  5. If the car is cranking, but engine doesn’t start or sometimes starts but immediately dies then do the following:
    1. If your instructions make use of the GRN wire of the PRO Module, then make sure the GRN wire of the PRO bypass is correctly connected and the connection is tight.
    2. Open the PRO module’s cover by removing the 2 screws on the bottom and change switches 7 and 8 of SW1 to [7:ON, 8:OFF] or to [7:OFF, 8:ON]. Make sure the switches 1-6 of SW1 are exactly as indicated in the instructions for your car model/year and if not, then change them accordingly. Try starting the car.​

If car is still not starting or if you have any questions or concerns please Submit a Request to our technical support team detailing the tests you have done and the results.


NOTE: when contacting our support team, please always indicate your car’s make, model and year.

Is the GM Security System (VATS, Passkey or Passlock) giving you problems?

Would you like to solve the problem permanently...

You are in the right place!

NEWROCKIES is #1 in the world. It was born to solve GM VATS System problems once and for all and it’s the only thing we do. Our PRO Module is a FULL VATS Bypass that gets rid of the system entirely, the Key part, the Lock part and the TDM (which is the brain of the system).
