Maybe Clutch Switch?

Gained access to under the driver's side dash.
As suggested by Flyman 27, located orange sleeve with 2 small white wires in it. Disconnected connector and checked for readings between the two wires going into the steering wheel housing. There is no difference in the reading whether key is in place or not, and irrespective of the key position. There is no resistance indicated.
I decided to test the individual wires to ground. One of the wires shows continuity to ground. I have not checked the schematic yet, but I would not think one of these wires should be grounded.
I am going to continue following the FSM procedure, but I am thinking that this wire being grounded may be an issue?
Feedback Please.
Thanks Guys.

Sounds like a VATS issue with the key.. you found the orange wires coming from the column, measured across them with no key, you should have no resistance. According to your info this is good

Now you added the key, but still got no resistance, this is not good. next steps (if it were me)

- measure across the pellet in the key and note the resistance
- find a place that you can purchase resistors and build a bypass
- put the bypass on the car side and see if it starts.

You could also test a second key if you have one, or get a new key made.

Here is the VATS code chart:
Key #1 = 0.41 K Ohms resistance
Key #2 = 0.53
Key #3 = 0.68
Key #4 = 0.89
Key #5 = 1.13
Key #6 = 1.47
Key #7 = 1.87
Key #8 = 2.37
Key #9 = 3.02
Key #10 = 3.73
Key #11 = 4.76
Key #12 = 6.05
Key #13 = 7.47
Key #14 = 9.55
Key #15 = 11.76


After this, if there is still issues, next is to by-pass the clutch switch to test it
