John,
I works as a truck mechanic at a Kenworth dealership. I’ve seen tons of midrange trucks come though with ISB’s and they all run an electronic pedal. I figured I could make one as well since the cable bellcrank in mine was sloppy and kinda a stupid design. I wanted to clean up the engine bay as well.
I use an International truck pedal assembly with a WC sensor mounted on a custom bracket and I use a jumper harness from the engine harness plug to the new pedal.
The idea isn’t original but I’ve never seen one in a 2nd gen.
