OVERVIEW
Unlock Cable Part Reference
- (A) 3-Blade Fuse Plug
- (B) Unlock Cable OBD2 Plug
- (C) Unlock Cable
- (D) Unlock Cable Box
Your cable also includes a 2-Blade Fuse Plug. This is not used for this vehicle application. Use only the 3-Blade fuse for this install. For your vehicle to accept tuning, you must perform a one-time unlock process on the Engine Control Module. With this Unlock Cable kit, you are able to unlock your own ECM using your tuning device without having to remove the ECM from the vehicle or ship it to us. Once the unlock is completed, you do not need to use the cable to install tunes or modify options.
Do not drive your vehicle with the Unlock Cable installed
- STEP 1 – Before installing the Unlock Cable, make sure you have plugged your tuning device into the vehicle, attempted to tune, and then updated your device using Update Agent 1.0!
- STEP 2 – Go to your vehicle and open the hood. Locate the engine bay fusebox and pull the two tabs indicated by the arrows, and lift on the fusebox lid to remove the lid.
- STEP 3 – Locate fuse number “57” (TCM/ECM), as indicated on the fuse box lid diagram, and remove it. Do not lose this fuse as you must replace it in this spot later.
- STEP 4 – Connect the included 3-Blade Fuse Plug (A) to the Unlock Cable and plug the Fuse Plug into the slot you pulled the original fuse from. Ensure that you orient the Fuse Plug so that the wire is coming out on the side closest to the driver, and furthest from the front of the vehicle
- STEP 5 – Route the Unlock Cable out of the engine bay, around the driver side A-Pillar, and through the open window.
- STEP 6 – Plug the Unlock Cable OBD2 Plug (B) into your vehicle’s OBD2 Port.
- STEP 7 – Plug the Unlock Cable (C) into the Unlock Cable Box (D).
- STEP 8 – Plug your tuning device’s OBD2 Plug (E) into the Unlock Cable Box (D). Make sure it is plugged in all the way, as it is a tight fit. Turn on your vehicle’s ignition.
- STEP 9 – Your tuning device should now power up. Select ‘Tune’ and follow the onscreen instructions to unlock your vehicleand enable tuning. Once your vehicle has been unlocked, you are finished with the Unlock Cable, and you will not need to use the cable to install a tune. Remove the Unlock Cable when directed by the device.
UNLOCK CABLE REMOVAL
Turn off your vehicle’s ignition. Disconnect the UnlockCable OBD2 Plug (B) from the vehicle’s OBD2 Port. Then, you may remove the Fuse Plug (A) from the vehicle’s fusebox. Place the vehicle’s original fuse back into its slot and put the fusebox lid back on. Plug your tuning device’s OBD2 plug (E) into your vehicle’s OBD2 Port. You are now ready to tune your vehicle without the Unlock Cable installed.
