I know the Painless wiper problem has been discussed before but most of the threads are either gone, or not very helpful. My question is how in the world does this thing work! In the kit all you have is one blue wire that it goes to the switch and that's it. I would assume you have to make all the other wires, but I don't have the slightest clue where the blue wire goes, or for that matter what the wire even does and the kit and the Painless site is of little help. Is the blue wire a control wire of something? How in the world is the wiper switch wired and how does it go to the wiper motor and wiper water pump? Any help would be wonderful. The car is running but I have no wipers, etc. I went with painless because I cannot afford to buy a complete replacement wiring harness for the Camino since mine was already MIA when I bought the car.

I'm trying to put an entire harness in a 72, how did you put yours in?
Did you pull the dash or not?

If you are using a stock wiper and switch-----
The wiper wire in ANY kit will go directly to the wiper motor.

The switch does nothing but switch grounds between low and hi on the wiper--and if equipped with a washer pump integral with the wiper motor switches the ground to that as well.

Looking at my 59 wiper harness----your 2-speed with washer will be similar----a black wire and a light blue wire from the switch to the motor and a dark blue wire to the washer pump.

ignition switched power (wiper wire) will plug into one position (center on my 59) of the 3 term connector and will be daisy chained to the washer pump.

With the wiper switch in the "OFF" position----the ground path is broken so the motor will not run.

FYI----VERY important that the ground strap has a good ground and that the switch is grounded to the dash----either of these not correct and the wipers will not work

Thank you Bryan that was the help I needed. Dave I pulled just the dash cluster and then made a wiring harness for the gauges and lights, etc; it made it a lot easier to wire everything up. I also cut a piece of sheet metal to cover the original hole and bolted the fuse panel down using the factory holes so if I decide to go back to original I still can if I can every afford it. I have about 16 hours into the rewiring of the car so far and just have the wipers and heater left to do. The one thing I like about the painless kit is it uses blade fuses, has two master fuses you can pull for safety, and the price is a lot cheaper compared to the price of getting a complete from front to rear original harness from the other companies; I just couldn't justify spending close to $1100 for a complete system when you can get a painless kit for $300. However if I could have afforded it I would have bought one just for the plug and play factor. One of the most important things to do when using a Painless kit is try to save all the plugs you can for the original harness because you will be using most of them with the kit. I would have liked to use an 18 circuit kit because of all the extra features, but I just didn’t have the room on the ’67 so I had to use the 12 circuit. For a 1972 go with the 18; it will fit your application. I did buy an 18 circuit kit that I most likely will use for parts as time goes by.

I've rewired a couple of rigs, including my Camino and the one thing to keep in mind is that the wiper is switched through the ground side. This allows it to keep running after you have shut off the power until it hits the internal pall at the park location.
