Question about 2005 Saturn VUE

05 VUE Electric power Steering wiring INFO for Land Speed Car.

Hello I am building a land speed attempt car & purchased a 04/05 Saturn Vue EPS off Ebay to install. What is the most basic wiring hookup? It has All wiring coming out of two plugs attached controller: PLUG ONE: two large guage wires ( 1 Black & 1 Red ).
PLUG TWO 3 very small wires( 2 Purple & 1 red).

I am assuming that the large leads are 12V supply for the steer motor & the smaller leads are eather to speed sensor or ?
QUESTION Can this be fed a dummy signal ? if so what Volt/amp or type. OR can the wires be connected together in some fashion to satisfy the controller to it least have it power up in a limp mode ?
This is a fresh pull from a running vehical so it is likely in good shape. But if only the mains are fed 12V nothing powers up.

I do not need speed sensing control since I will design the steering arms & box around the output of the unit.
The Car I am building is based on a Fusaloge from a Lear Jet 35 using a Volks wagon bus front axle & two over clocked 2002 Supercharged 3.8 Grand prix GTP front wheel drive trains mounted as driving rear axles.
I am 3/4 complete. It looks strange but is very streamlined & light.
My wife & I plan to drive it to The SCTA time trial meets as more of a Joke But given the numbers it should pull 200mph plus (empty of extra seats , sound system etc.).
REALLY COULD USE YOUR HELP as I am an old school racer & new to EPS. ( and anything to do with wiring up to a chip based anything).
Thanks in advance, August Sommerfeld REPLY TO

The two large guage wires are constant power and ground. The small red wire is an ign power, and the 2 purple wires are class 2 data lines. I've recently heard of a company making a dummy module. Something with river in the name.

Where is the fuse location for electric steering for 2005 Saturn Vue

The power steering fuse is part of the ignition fuse, it uses power from ignition to engage power relay system on steering column next to the electric powersteering motor. Check the two wire port for ground and power with vehicle running. Mostly all saturns with electric power steering are all under a safety recall, with free replacement.
