Rolling anti lag from windshield wiper switch

Hey folks so i came across some videos where people some how wired their rolling anti lag into their wiper switch so i was wondering how to go about that?

What ECU are you running? It's likely wired in as an input to the computer and then the computer triggers the anti-lag. But without knowing your setup, it's hard to say.

Repurposing an existing button like a windshield wiper button to control an ECU function involves rewiring it so the signal goes to the ECU rather than the squirter motor if it's a simple electrical system. If it's a CAN message, things get a bit more complex. As Bryan said if you can provide more info, we can provide more detail.
