91 suburban cruise control elimination

[jjmorrse]

I have a 1991 suburban, 1500, 350, r700 trans. I like to simplify my vehicles, chalk it up to old hotrodding days. I have eliminated the parts of the cruise control from the engine bay, but still have wiring and a vacuum line under the dash. I am not really familiar with the tbi systems, so I am concerned about eliminating something that gives info to the ecu. The vacuum line to the cruise comes in with the cruise wiring and attaches above the accelerator pedal what I will call a switch/controller. What wiring and components can I remove without causing problems with other sysyems? I am afraid that if I remove too many components/wires, the suburban will not know its speed. Thanks
