Got a VDO Visions Tachometer that I'm trying to hook up and I've misplaced the instructions. I'm using a pre-wired harness and the instructions say to hook up a purple/white wire to the sender, the red/white wire to the battery connection and the black wire to ground. The only identification on the back of the gauge is terminal numbers two, three and four.
