    Does anyone know if 74's came with a delay switch, I have slow/fast/push in washer fluid, and it looks like there is an empty space above that switch that seems to have some sort of ribbon contact, like maybe I'm missing a sliding nob. Any suggestions?

    I don't think so. I don't think delay wipers came along in K5's until several years later than '74. The factory delay wiper switches that I've seen from the era of the wiper-switch-in-the-dash just had a knob on the switch, that you turned to control the delay. The on-off-delay control was integrated with the delay time knob. It was a rather odd arrangement.

    If you were looking for intermitant wipers you can get delay box type units that just slice into the existing wiring. I bet JC Whitney or maybe even the locak CSK/Pepboys has something like that.

    I was going to do that if I couldn't find out what that hole is(its about 5/16 X1" 1/2) its is right above the wiper switch. If nothing else someone has to know what went there originally.Like I said before there is some sort of ribbon contact in there and something is missing from in front of it, I thought it might be a sliding nob that would control the wipers any other thoughts ....

    My '74 had a Fiberoptic ribbon going from a light bulb in the instrument package over to the graphic above the switch that says "wipers". That's what made it visable at night. Other than that no extra holes....
    I am in the process of adding the later model delay switch and wiper motor....I can let ya know how it goes if you're interested.

    I looked at the dash in my '75 tonight. There isn't a hole above the wiper switch. Sounds like someone may have done a bit of custom crafting on your dashboard. [​IMG]

    Also checked a '74 factory service manual that I have and it makes no mention of a delay feature, just lo or hi speed. [​IMG]
