E 350 V8-5.4L (2008)
The Ford powertrain control strategy will not allow tor this operation, whether using SE IC, or an attermarket controller commanding engine speed
directly at the toot pedal throttle or through the Ford data-link connector. The PCM will typically react by restricting power and engine speed, and
possibly varying speed while searching tor a solution. It may not do this immediately, but atter days or a week ot customer operation. It also will not
guarantee a 1:1 transmission ratio command, typically required by split-shatt PTO applications.
Circuit Descriptions for SEIC and Customer Access Signal Circuits
All circuits lead back to pins on the PCM.
