new overdrive question

On the T-85N overdrive, there is a wiring plug that has three wires. Two of the wires go to a canister or solonoid on the side of the tranny (assuming one is batt. and the other ground) The remaining wire goes to another canister on the side of the tranny (I'm also assuming this is a Batt. wire. My question....do two of the wire go to the batt. via a toggle switch to switch the overdrive in and out, and the remaining wire a ground?

Thanks
