No, I didn't do any front vents. With the rear being vented incoming air should flow over the engine & clutches better now that it has a place to escape.
The tether is plug n' play kit from Poo that I took off my IQ. Key still works.
Where did you plug yours in at? Back of the key fob?? If so what do you do when you remove the hood? Maybe I'm not seeing this right??
