47-55.1 49 Chev 3100 Horn issues - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hope someone can help me here. Installing a new wiring harness on my 49 Chev truck. When I hook the wires up to the horn it blows constantly. Was told to disconnect the ground on the horn button but when I plug in the horn relay the horn still blows. I have RED,Green & black wires going into the horn relay switch. Following the black to the ignition switch as it is a horn relay ground, the green wire goes to the horn. Any suggestions?
