I want to put a power seat frame in my truck. There are three wires comming out of the floor into a plug. This plug is mated to another plug with two wires comming from the seat. Is the third wire for the power seat operation if the truck had that option? If so, how would the seat operation circuit be completed? Where's the second wire? Also. there's a place for the fuse relay in the fuse box but is is empty. Would you just need to plug in the relay fuse and the power seat plug into the existing plug under the seat for it to work or is this just wishful thinking?
