My thanks to Ralph Gosnell, he let me borrow an original factory wiper interval wiper relay harness. I have since done some initial research and it looks like I could make these available, with a new relay.

I could make the harness available in the $40.-50. range, and the relay is available at cost for about $65.

The harness would come with detailed pictorial installation instructions and the wires would be correctly color coded. It would take careful scrutiny to see the difference from my harness and an authentic factory harness.

Please respond to this post if you would be interested in getting one of these harnesses. I suspect I would just provide the harness and tell you how/where to obtain the relay. Your response is not a committment to buy, I am just gauging interest to see if I should develop this idea further and order parts.

Thanks! Jeff

Apparently I'm out of the loop. How does the delay work?

Yup, I'm in! I think I already have the relay from years ago before I knew I needed to create a place to put it.

Jeff, I'd like to wire in a relay, but in my '70 with the switch on the dash. Is it doable?

This sounds like a very practical idea; I'd also like to have one.

I think I have a socket for the relay - just no relay? I have a '73. Is this possible?

Where do I get a relay from?

Oh - and what are common causes of the wipers not retruning to base when they are switched off?

Fiid.

The 74 model year came with some of the harness in the car. The relay needs a socket and short harness to connect to the body harness. The relay / socket bolts to the drivers side cowl support. You also need to have a suitable wiper lever with the extra contact, and I think the column cover needs to be trimmed to allow the lever to be used. To install in an earlier car would need a fair bit of extra work.

Jeff, Count me in. I always wanted the interval feature. Provide good instructions, though. I am not the most electrically-inclined, but I can usually follow a wiring diagram. (IMG:style_emoticons/default/wacko.gif)

Martin,

Your 74 should have the wires in the body harness. I had to unravel part if the wrapping to find the ends, but they were there. Just around the brake fluid reservoir.

If this is like what my '95 VW Jetta implements then I recommend it! Not sure if I will commit to buying one due to the extra column work involved for a '73 and I have bigger problems to address (rust).

yepp, the later cars (i think '74 and onward) have the wires to hook this up.
actually, all you need to make it work on a older car is to run the brown/black wire somewhere to the inside of the car and add a switch.
all the other wires connect to the wiper motor which are the same for early and late cars.

btw. this is NOT a wiper delay, this is a "intermittend" switch.

what it does is:
if you move the wiper lever towards yourself to activate the windshield washer the wipers will come on and run 4 or 5 turns, then shut off.
that's all!

if you have a electric pump, you can extend the brown/black wire to the pump to also operate the pump when moving the lever. (same result as above).

earlier cars don't have the needed switch on the wiper lever at the column (really early cars don't even have the lever, they have a knob on the dashboard).
the easy way to test if you have the needed switch in your column is to find the brown/black wire that exists from your steering column into the wire-harness.
there is a detailed reference to this complete "intermittend" wireing in the Haynes Book somewhere in the electrical pages.

some of this is shown here:
Wiper Relay Instructions

hope this helps,
Andy

No, if you move the switch down a notch from OFF, the wipers run at a pre-set interval of every 2 seconds or so (I have not measured the time).

I think the wiper relay does both features.

Did you break out the plastic tab so you can move the wiper switch down? I don't remember on the washer, as I do not run a washer (I hate the excess washer fluid running all over the place).

I have a '74, got the parts off a '74 2.0 and found the original wiper switch did not have the extra contact/wire terminal for the feature. Checked the switch from the 2.0 and it was there! Same P/N. The brown/whatever wire was in the harness.

i actually tested it for that said function before i assembled the unit.
however, the unit i have did not have an extra position below the OFF.
i could not move the lever down and i did not get any movement on the wipers.

how can there be 2 completely different "modes" if there's only ONE control wire from the lever to the relay ???
if you take the assembly off the steering column, you can actually see the switch closing on the opposit site.

still confused, (IMG:style_emoticons/default/confused24.gif)
