Intermitant wiper switch for 66 chevelle

Anyone ever put intermittent wipers on a 66 Chevelle? I'd like to set my 66 El Camino up with them. Can I just get a switch from a car with intermittent wipers or do I need to perform some electrical magic? Also like to set up 4 way flashers on the car. Any ideas will be appreciated.

You can find someone to do a little electrical magic. I've built this circuit a couple times, works well.

Re: Intermitant wiper switch for 66 chevelle

The problem with the circuit posted is the fact that the 66 wiper switch has no power to the switch itself as the switch only provides a ground path for the motor. Aftermaket companies such as Newport Engineering or Raingear offer new switches and motors to allow you to have modern day pulse wipers on your classic.

Re: Intermitant wiper switch for 66 chevelle

You can easily adapt the circuit to work with ground as the trigger. You could hide the potentiometer at the bottom lip of the dash. Turn the wipers on, then control the delay with the potentiometer or pot and you're good to go.

I just had to rewire my headlight switch to provide a ground to the silverado fuse box for the headlight relay instead of putting out +12v to the headlights. The wiring systems in these cars are pretty basic, you'd be surprised with how much you can get away with.

I haven't had time to build this circuit for my car, think I've got the parts needed, just need to sit down and do it. If your windshield wiper switch is the same as the 64 it's a single male spade connector. You can terminate the wires with spade connectors so installation/removal would never mess with the car in any way besides having to tap the fuse box or a power wire for the circuit.

*EDIT* Matter of fact I was working on this before Christmas break. I had the circuit setup to use a board router to spit out some quick boards, but ended up with some cheap breadboard (red lines on the right). Was working on moving the components to the breadboard in a way it would be easy to solder up and install in my car. (see pic, "finished" board on left, empty breadboard on right)

Hotwire, I get what you're saying, but for the average guy not into electronics,it is probably easier to buy a pre-engineered kit to convert to intermittent wipers. Many people hate wiring/electrical issues as it is, so building your own circuit board is well beyond their skill level or desire. Nice idea though.

Rick did say electrical magic, saw my time to shine.

Re: Intermitant wiper switch for 66 chevelle

DO a search.... I recall someone identifying a wiper switch that will intermittent our 66/67 motors and I beleive it may have been from a 70's Chevy truck or full size. AS many of us avoid rain driving, I never bothered.

For about $75 I installed this on my 72; I think it works on a variety of gm switches:

I also installed his Headlight Auto Off circuit which I really like. I just leave my switch on (I like driving at all times with the lights on) and don't have to worry about turning them off.
