Before I contact FRPP about this, I would like to know if anyone here knows what is required to install cruise control with the M-6007-M50 5.0L Engine and the M-6017-A504V engine control pack.
The FRPP 504V installation instructions specifically state that the system as supplied does not support cruise control. Another poster said that additional wiring is required, but had no specifics. The Drive by Wire throttle set-up may complicate the issue a bit.
Any help out there?
