I know someone must have replaced their TH-350 with a TH200-4R...There is an electrical plug on the driver side of the 200-4R. It has 3 wires. [U][SIZE="4"]Where do they go and what do they do. U]I'm about to make the swap to get some gas mileage, and to get my rpms down on the highway. With a 3.73 gear, I must be turning 3000 rpms at 65mph. Please give me a private message if you know what to do with these wires.
