How to Install Cruise Control in Your Car
You may think that it is difficult to install cruise control into your car. However, it is not that difficult and you can install cruise control in under an hour. There are kits available that will contain everything you need to install an aftermarket cruise control. The vast majority of vehicles will already have cruise control or are ready for the installation of cruise control.
Step 1 - Unhook the Battery
As with anything connected to the power source, it is important to unhook the battery cable. You need to leave the battery unhooked for about 10 minutes so the power is released from the airbag system. You will need to position your key to the accessory power position so you can have the steering wheel unlock. If the power is off then most steering wheels will not turn. Turn the steering wheel enough so that one of the airbag screws is facing the floor.
Step 2 - Move the Airbag
Unscrew the bolts that secure the airbag and lift this away by about 6 inches. You will be restricted by the cables and wires that connect to the airbag. These connections are very important and you need to be careful you do not pull anything out. Unhook the airbag cable connection and be very careful as it contains a small amount of explosives.
Step 3 - Find the Cruise Control Connection
Inside the wheel should be a white connector that is for the cruise control. This is normally close to the horn mechanism. If you are having difficulties finding the cable, then check with your vehicle manual. You may also need to cut through some mounting hardware in order to place the cruise control switch. This will depend on the vehicle. Attach all the wires.
Step 4 - Mount the Switch
It is very important that the switch is mounted securely. You will have brackets and several mounting screws. Once this is mounted you can reattach the airbag and place it back in the steering wheel. Tighten the bolts and if you have a master switch you can install this near the steering column.
Step 5 - Install a Cruise Control Computer
If your car needs a new system or is not cruise control ready, then you will also need to install the cruise control computer. Normally this is near the driver’s side kick panel, though the location can vary depending on the vehicle. Most cars will have studs where the computer smoothly fits over. There is normally a harness specifically for the computer.
Step 6 - Add Other Parts as Needed
You may also need a sub-zero unit and an additional switch. This is normally by the engine bay and is held in place using three bolts. You also may need a cruise actuator and additional cruise switches. It is best to determine which parts you need first to ensure you have everything you need for the cruise control.
Step 7 - Calibrating the Computer
Setting the program for the computer is fairly complicated. Particularly for those that do not understand programming. You may be able to get the manufacturer to calibrate the computer. There are many online guides that can provide you with the details you need to calibrate the computer properly.
