The harness should be on top of your fuse box. Pull the panel off under the steering column then to the left will be main fuse box. Drop the 4 screws and there will be a loose harness. I remember there being a couple orange wires but don't know the configuration of which wire to which switch. If there are any questions do a search. I remember seeing a nice description of the wire colors to each switch. 2 are rated for 10 amps. 2 are rated for 30 amps. good luck. easy access
