• Raise the car.
• Remove the plug from the hole into the passenger compartment.

If the car has a rubber grommet without any space for more cables 

• Remove the existing rubber grommet and replace it with the rubber grommet from the kit.

If the car has a rubber grommet with space for more cables 

• Cut off the tip of the unused rubber teat and route the cable into the passenger compartment.
• Thread on the rubber grommet from the kit. Lubricate the cable with normal soap so that the rubber grommet slides easily. Route the cable through the hole and press in the rubber grommet.
• Make sure that the cable's heating hose is in contact against the rubber grommet.
• Secure the heating hose with a tie strap.
