reviving intermittent wipers


New Member
Hi i'm trying to bypass my integrated control unit in my 91 civic si. I tried replacing it but the circuit boards on the original and the replacement (ebay) are corroded. Intermittent wiper function doesn't work. I got a "universal" intermittent relay circuit but can't figure out how to connect it. It looks from the wiring diagram that the green wire going into the ICU controls the relay trigger side and I get 12v when the ignition and INT switch are on. I just can't figure out how to connect the wiper motor. This looks like a ground side switched system, no? Blue/white 1 and Blue/white 2 look like they are related to the park feature and i don't want to mess that up. If I ground the blue wire coming out of the motor it blows the fuse. Please help!
