Step 1: Ensure both the steering wheel and wheels are completely straight and disconnect the battery

CAUTION: Disconnect the battery negative lead using a 10mm socket before proceeding with the installation!

 

Step 2: Insert the airbag removal tool directly into the concealed opening located in the backside of the steering wheel until you feel the spring resistance. 

Repeat this process on the opposite side and the lower side of the steering wheel. 

Disconnect and detach the airbag, horn and information connection plugs, then remove the airbag carefully.

Afterward, proceed to unbolt the steering wheel center bolt using a 17mm socket to take off the factory steering wheel. It’s crucial to maintain the clock spring ring in its original position without spinning to prevent any damage from occurring due to excessive turning. 

(If you damage the clockspring during this step, you will lose all steering wheel functions after installation. Then you need to replace the entire clockspring)


CAUTION: Risk of injury. Handle the airbag unit carefully, ensuring that the battery is always disconnected and the airbag is always facing upwards when it is being set down!

CAUTION: Ensure a tidy and secured route for all the connection harnesses!


Step 9: Install the Madtrace Airbag Resistors (#7 on the Product List) onto the airbag harness, then carefully wrap the resistors with electrical tape to prevent them from falling off or having poor contact. After that,reinstall all the removed trims or plastic pieces back into their positions.

Step 10: Insert the two yellow airbag harnesses through the back side of the adapter hub and insert the quick-release harness through the front side of the hub


Plug the harness from the quick-release harness

If you have the version shown below, make sure to connect the two black ground wires.
