911R Steering wheel, Horn button info
Mike,
The 911R does have a horn, the button is not on the steering wheel, it's on the dash just to the left of the head light switch, it's a small black button about the size of a quarter. The center of the steering wheel then has a Fuchs wheel hub cap in place, think is was just for show. Further on the R dash layout, left of the horn button, are two push/pull type switches (718 part #), they are for the twin ignition system, each switch controls one circut of the twin plug system, so you could check each set of plugs to isolate any missfire. The steering wheel is a 3 spoke 380mm dia. leather wheel with slots in each spoke, The R parts book shows it to be a 906 part number. Since the R has the outer two gauges removed, the clock on the right, and the gas/oil tank level on the left. The factory placed a red light just above the radio cut out in the center hole, this light was a low fuel warning when the tank was low. The ignition switch does not have the steering wheel lock, and the glove box door, radio, heater vent controls, and trim were removed from the dash. The parts book also states that the "framing for dashboard covering" is different from the series car, this may be lightweight meteral.
