2006 Lincoln Navigator. What wire is on the A/C compressor pulley and if cut can stop the truck starting?

Question edited for clarity.
Question moved to Yes, Model category.

It is one of the most complex electrical systems on a modern vehicle. You will only get the full wiring in a service manual or from a subscription with AllData. You can however usually bring up part wiring diagrams. The search query is

if the ac belt doesn't involve anything other than the ac just leave it off for now and replace it at your leisure

You don't do anything, the control module will start the pump and reset itself, If that doesn't happen you have still got a problem.

If you are bypassing the solenoid when you "bump" it, the solenoid probably needs replacing.
If you are shorting to the small terminal and activating the solenoid, then the solenoid is OK and either the ignition switch or the wiring connecting the switch to the solenoid are faulty.

The air bags are leaking, replace them as a pair.

It is a near useless add-on to the ABS Braking System

It cuts off fuel injectors & thus engine power when you need
control over it,mostly slipping in snow

It on my Lincoln slams on the rear brake & you stuck in snow

If I ever found a way to cut the wires & shut it off I would make
it public knowledge

I have the wiring diagrams & have not yet worked too much on it

On my car Off is On & the owners manual couldn't be figured out
if you had a Doctorate Degree

If the Light is Off it is the system is on,go with that

Your mechanic should have known NOT to hot wire anything in the vehcile. Everything is run by computer/s. when you start hot wiring things you start to put voltage or higher voltage to things that should be controlled by the computer. Have it unhot wired and fix the problem. Putting higher voltage to things that run on 5 volts tends to burn up computers. Very costly....

im having the same problem and cant figure it out. i just found the wire that tells the starter to turn on and cut it and put me a push button switch in so that it only engages when i push that button.

Check all your fuses. in the dash if any and in the hood if any. Sounds like the circuit overloaded and shorted out.

i know this worked with my 99 navigator 32 valve used a viper car starter.
