Yes the APS has no hose on it but is otherwise the same as IAPS1 and IAPS2, both of which have hoses to their correct intake plus wires to their correct port (don't mix 'em up): 5JW-82380-00-00 (fits all three spots). For wiring and hose explanation see the Documentation Forum's Table of Contents.

Intake Air Temp 'Thermosensor' is 5PX-85790-00-00. I'd hesitate to buy Thermosensor used because if the sensor is over-tightened when installed it becomes damaged and its hard to know by looking at it.

Check: For your Yamaha Parts, Yamaha Accessories and Yamaha Apparel to verify part numbers for your model year in case differs, and for best known prices.

If you're planning on converting to carbs save your money for your rebuild ... the Warrior motor will run w/o these sensors on the current F/I system
