Mine is a 2001 with cruise control. From what I have read on the various forums the old switch just unscrews from the master cylinder and the new harness connects onto the old connector and to the new switch. Sounds like a quick straight forward repair. You must have a problem somewhere else in the circuitry. Something in the circuit that should be "hot" is finding a path to ground. This type of problem can be very difficult to locate. You will need wiring diagrams to start with. |
