Anyone have a source for Chevelle/ElCamino wiring diagrams? Windshield wiper circuits in particular.

I was looking for multiple years, thought there might be some online references. Like this:

Bill,
Let me guess, you're looking for info to do research on for a delay wiper system mod for the Chevelle line....
The biggest issue will be the '68-72 with depressed park (hidden wipers) as you would not want the system to "park" between cycles but remain at the bottom of the windshield. I've done my own research and ended-up saying "Why reinvent the wheel"? (I've got a '70 with depressed park). I ended up using GM's own design and tooling. I took a switch that was used in the 1980/1981 Camaros, disassembled, clean and modified it to work in my dash. Looks 1000% stock, but has the ability to rotate the knob to adjust the "pulse" delay. In fact, it is backwards compatible too, if the electronics (GM factory pulse board in the wiper pump assembly) take a crap, I can install a stock system and the switch will still work on basic controls.
*HINT* GM used a "end of sweep switch" so the circuitry knows the wipers are at the bottom of the windshield so the delay doesn't take place when the wipers are in the middle of the windshield and you look like an idiot driving
The earlier years should prove to be less of a challenge with the wipers being no depressed. But the '64-'72 Chevelles all use the same basic idea, wiper motor has power at all times even when the wipers are not active. Dash switch sends out grounds to specific wires for functions.
See my responses in this thread for wire functions on the hidden systems:

Yes Joe, I am doing a bit of research to roll out a wiper delay. I currently market one for 60-72 GM trucks elsewhere. So, were Hide-Away wipers an option for 68-72? Or were they standard equipment? I may not even fab something for those model years as there should be enough interest(I hope)from owners with non Hide-Away's. Looking at wiring diagrams for Nova, Impala etc. GM did not stray too far from it's 12V to the motor all the time with the wiper switch completing the ground circuit. With that said, I may have plenty of work even without Hide-Away owners.

Not so fast, even I know I cannot sell it(yet)A mod ought to know that!
Re:Advertising on Elcaminocentral.com
If you provide a service, sell and/or manufacture parts then you need a vendor tag.
Have you been contacted by a moderator to contact sales?
Sincerely,

No worries, I am going to sell here but I have to pony up $50/mo. per Tier 4 forum to advertise. I just want to insure that my money is well spent. As I indicated earlier, I have a working wiper delay that installs with no harness cutting. Once I become a vendor you will be able to see more of it/purchase it. By the looks of things here, it looks as though I have found a good place to set up shop!
