I'm going to update this for the next guy. My 1100c is a 2022. I had to use the middle wire. The middle wire had 12v+ when switch was on. The bottom wire did not.
I ran the wire from the switch to the NC terminal. I ran the wire from the wiper motor to the Com terminal.
The part I can't wrap my head around is the connections for Com and NC. I don't understand why the Com port runs to the switch and not the wiper motor.
That is what it was. I have a buddy that swears that the common should run to the motor and the NC should run to the switch. I don't know enough about relays to know.
I am trying to wrap my head around this project. I see where some folks used the middle wire for their setup and some used the bottom. When the wiper switch is on, is it sending 12v positive to the motor? I'm not sure if my board was defective, or if I used the wrong wire.
I tried to install this tonight. My 1100 is a 22 so I used the wire in the middle like others did. As soon. As I turned on the board, got a little smoke and it melted some of the board. I'm not sure I understand what happened. Is the board sending 12v positive or 12v negative to the wiper...
My $26 board came in today. When it's all wired up do you flip the OEM switch and adjust delay with the knob, or will the knob turn it on as well?
My Father-in-law drives my 1100 from time to time and I think it would be easier for him to just work the switch and we leave the knob set.
