This delay timer was the cheapest way to replace the very expensive and hard to find Bosch intermittent wiper modules I needed. It's well built and works great, but it is very easy to install incorrectly. The wiring diagrams, while very clear and show how the module works, aren't applicable for many wiper motor circuits. You will have to have a wiring diagram or know how your wiper circuit is run in order to have them work properly and not burn up.Second, you need to use these modules to fire a relay to run the wiper motor. The traces on the board can not cary enough current to run a wiper motor and will burn up.The way I found that worked for me is to supply 12v to the park switch and use this module to fire a relay that sends power to the low speed wire on the back side of the wiper switch.

I drive an old 1977 Chevy C10. After years of frustration of one hand on the wheel, one hand on the wiper switch, I was determined to put in delay wipers. Every other option I saw was hideously overpriced, so I went with this circuit for the price. The reviews were mixed, but I’m smart, I assured myself, so I thought it would be a breeze. Alas, no.My advice. 1) Start by connecting the +12 and GND. I ran a wire for +12 from the fuse box to the board, and I ran the GND to the original wiper switch. 2) Of the three remaining connections, you have NO (Normal Open), COM (Common), and NC (Normal Closed). Since my wipers activate by grounding one of three wires, I pinched wires between the ground and lo-wiper tabs on the switch into the socket. Crude, but it works. 3) I ran the ground wire to COM and the lo-wiper wire to NO. So, here’s how it works…With the key turned on: when I turn the delay knob on, it clicks, and the timer starts. The relay closes the NO switch to ground and the wiper starts. The relay clicks off and the wipers finish a single pass and return to the bottom. I can set the delay as needed, or turn and click to the off position. The original wiper switch works just as normal. Yay!

Worked great for my 1981 Toyota pickup! Check your voltages prior to just hooking it up because if you hook up the wrong way it will short. Take your time use a voltmeter but it does work! I spent a lot of time trying to find something like this.
