When the negative terminal is connected to the battery the starter starts cranking by itself, even after ignition. Ford said my solenoid is wired backwards but I tried every possible combination but still doing it. HELP! lol

Disconnect both small wires from the solenoid and unmount it, leaving it isolated from ground.. If it still happens the solenoid has to be bad.
The easy way to find out what's wrong would be to probe around with a voltmeter. You'd isolate the problem in 30 seconds.

Remove the small wire(s) that is connected to the solenoid. This is the control circuit that closes the solenoid to provide the high amp supply through the large battery wires. If the starter still wants to crank over then the solenoid is shorted out internally and needs to be replaced. If it doesn't crank then but cranks when the small wire is connected (and the key is not being turned all the way to the 'start' position) then you may have a short in your ignition switch that is causing this circuit to have power when it shouldn't

Three wires needed for it to work, from the battery Positive to the sol. from sol. to starter. The wire from the ignition switch and sometimes to 12v to the coil to boost voltage durring start up. 12v to the pionts all the time will burn them up. Ground for the Sol is provided by it being mounted to the firewall. Sounds like a bad sol. take all the wires off and check it with a meter to see it it is open between the 2 large posts. pul the small wires off and just leave the large one. if it still cranks, sol shorted. if not check ignition switch.

Two things come to mind.
1) Contacts inside the solenoid have welded themselves together and won't disconnect.
2) You have the solenoid wired wrong.

Check all related cable connections to see if there is a "clean" ground..
It is also possible there is a short within the starter/alternator.
