Discussion and questions related to the course PDM Installation & Configuration
= Resolved threads
So I want to control the wiper motor of my Honda Civic with the PMU-24 that I'm installing.
Now the Honda wiper motor is wired a bit differently compared to other (non Japanese) car brands. Where is has a single power supply and the Hi/Lo pins are connected to ground through the OEM wiper switch. I've added some of the original schematics.
Now I have a couple of questions:
1. According to the manual of the PMU it would mean I will have to change the direction of rotation. I've been told this should not be problem, is this correct?
2. My current plan is to connect Hi and Lo pins to two of the PMU outputs. With Lo to the dedicated pin for that and the B-pin to ground. The As-pin to an PMU an input as the Park switch. Finally the E-pin to ground. Is this correct? I'm not quite sure about the park switch wiring.
Hopefully one of you can help me out and/or has expierence with wiring an Honda wiper motor to the PMU.
Thank you in advance!

Hi! If You will change the polarity, you will have a positive power supply in the body of the washer, when it goes a parking switch
The attached example is to suit a MoTeC PDM but the theory is the same.
It's not ideal to wire the motor in reverse so instead you use an external relay on the low side to switch from the low speed to the high speed winding.
