guess you would need to by all sensors to connect to it?
No, they plug into your diagnostic port and pull the readings from the ECU.
yea saying that looking at the picture properly its not much bigger than the diog plug for the car...if you could do away with the vent then could look good...Was thinking drivers side air vent. There not very big, only look about 2 inchs big.
can see why air vent is a popular option. however, i like having mine.... cold air blasting on hands, keeping them dry for better grip
