I have a wiring harness (in great condition) and have no idea what its use is for, any help in identifyng it would be greatly appreciated. On the harness there is a "white" tag with the following numbers: "3764710 64312" If it helps, when I got the harness I was initially told it was for a three speaker dash. The harness has one large gray plug with five spades that runs out to a long wiring group that has four smaller black plugs, of the four smaller plugs, two are made for round connectors and two are made with spade connectors. Hope that helps.
