All the gubbins in the 2nd pic is all to do with idle control when the A/C is on. Obviously if you dont have the A/C, then it is not needed. Rip it out and blocl the ports/nipples on the throttle body As for the tank breather, DO NOT block it off, let it breath, It breathes for a reason... Mine is plumbed into the black box on the near side chassis leg As for the sensor in the first pic, all i know mine is gone and ive no issues, no idea what it is for. Old modification now (for mr anyway..)
