Can I disable the security system so my truck Will stay running

My fiance said to wire the middle wire and the one closest to the driver door together, use the screwdriver as the key and go through a process of rebooting the security which is 3 sets of 10 second and 10 minute intervals. So you turn the key to the on position then crank it over, release the key so the ignition stays in the on position and allow the vehicle to sit for 10 minutes. After the 10 minute period go back to the truck and turn the key to the off position for 10 second, crank the truck over and then leave the key in the on position again to start round 2 of the intervals. You will do this a total of 3 times, after the 3rd time the truck should start up. Good luck!
