The yellow cable is the Holley 0-10 volt cable or any system that can accept 0-10 (S-414). The black cable is the Generic 0-5 (S-415).

New lower price and better sensor. There are many distance Banner senors (many are familiar with the yellow plastic unit) to choose from - some not so good for ride height. EFI tuning expert Glenn Payne has worked with Banner to determine the best sensor for RH at the best price. My kits are based on Glenn's research - including setting up the sensor to NOT go back to zero after reachin maximum distnce - a key issue with some sensors.
