Does anyone have the dash mounted idle adjuster found on some early model 89/90 CTD's? I have seen the parts manual breakdown of this but nothing is offered (as far as I can find out) as a unit. The mechanism mounts onto the bracket on the firewall next to the foot pedal and has a cable that goes to the dash. I assume it has a twist lock cable and lets you raise the idle speed so you can operate some power take-off equipment. Any advice would be appreciated. Thanks in advance.
