My first update to this thread was Post #36 up top. I have had Leon edit that post because I was wrong: Cole Hersee made several SIMILAR but not identical switches, and they all have different wiring to some degree. This was more important than I originally thought.

Two nights ago I hooked up the whole shabang using a Cole Hersee 75600-04 on my test bench and FAILED. I couldn't figure it out. I did some digging tonight and found a few little nuggets of info.


Apparently there was an update to this thread from 2004, and look at the last post of that thread:

Boy I wish I had read that before buying the switch, but no matter, that's done.
Back to the drawing board.


Here's something cute and somewhat related to this thread: again, no part numbers or details(makes sense, he was trying to sell his product), and they're not around anymore...

I would like to quickly bump this thread.

I ordered and received a used Cole Hersee 75601 switch and tested it, wired it exaclty like blue_69 did in Post 4 http://67-72chevytrucks.com/vboard/s...963#post215963

It works perfect.
The specific switch part numbers have characters at the end such as 75601-08, or 75601-04, 75601-XX , it sounds like those last two digits don't necessarily change anything, it's the first five characters that need to match: 75601.

So the DIY intermittent delay wiper mod for 67-72 GM trucks only works if you can source a now-obsolete and not-for-sale-new 75601, try eBay, they're not unobtainium yet.

It sounds like they were already obsolete when this thread started, and thats why this thread and other "delay wiper kit" threads died.

I'm sure they'd sell if someone could find 10-20 of these switches and followed blue_69's wiring.
