I ordered new switches from LCM, they are wells, just wondering how to wire them up.The old ones have the two wires connected to it.The new ones do not look the same, they don't have anywhere to connect the wires? I have a 1984 Chevy 4x4 Scottsdale, with new 350. And also since the engine was installed my intermediate wipers don't work and the washer pump will click and come on but no water?
