It's just a wire so you can add to it and use one of the locations by the cruise actuator which is easier to remove than the IP. You'll need the single pin sender and either a new reducer to keep the double-pin sender in place or move the plug to the old location. Problem is, you need to shave down a 14mm of whatever hex bit you need for the plug in the tight confines by the IP. Seems fitting a proper sender, $10-15 new, is less work than the alternatives. Hook up the wire to the double pin sender and see what happens.
