Hello! Haven't posted in a while. I finally got a harness for my F to M dash swap. It came with an Intermittent Wiper Delay Module but the harness only has a plug for a 2 speed switch. The module has its own white plug underneath the dash. This is my first time seeing a IWD module and im not sure what it does or how it works. The harness came from a 79 Lebaron and the IWD has a white case.
