IDIDIT Steering Column / Wiper Electrical Issue

[rhamer88]

I’m having a unique issue with the wipers on my 1984 C10, hoping someone smarter than me can assist with a solution.

The backstory here is that I installed a new IDIDIT steering column which comes with a new head light relay and wiper relay.

The issue with the wiper relay is that it works in a reversed polarity than the factory setup does (IE the feed wires for low and high speeds output as a 12V lead instead of a ground). I had to make my own wiring harness and basically reverse all of the polarities. So now the feed wire going into the motor is ground, and the leads for the low and high speeds toggle positive, which then activates the wipers.

So the issue I’m having is the park function is not operational. The new wiper relay has an output for park (which is a ground signal when the wipers are off). So what I need to know is if there’s a place I can wire the grounded park lead on the motor assembly to make the park function operate correctly.

Any advice or insight would be greatly appreciated!
