ok had the battery disconnected for 3 days and hooked it back up today and truck started up fine and no security light on the dash at all. So this is a way to get rid of the passlock deal.
That security light not coming on seems really odd, especially considering the bulletin/mod says this:
When this modification is performed and the switch is set to the ON
position, the theft deterrent feature will be disabled. When the theft
deterrent is disabled the SECURITY telltale will light up indicating that
the theft deterrent system is NOT functioning.
Start the engine with the ignition key (modification switch must be in the OFF position).
Turn modification switch to the ON position (contacts open). The Security Telltale will
light up indicating that the Passlock System is inoperative. Once the security telltale has
been on for at least 5 seconds the vehicle can be turned off and then remotely started.

Virginiabound also notes "...The security light will stay illuminated..."
Wonder if he has ever disconnected the battery on a vehicle which has that "three-wire plug on
the top of the ignition" unplugged, to verify whether that is a permanent fix or not.
The way I understand things is, disabling the passlock by unplugging the key portion or cutting the yellow
data wire(switch install)will eliminate annoying no start conditions related to and caused by the column parts of
the system, but only until the day the battery dies at which point the passlock will be need to be hooked
back up, only in order to restart the vehicle.
Wouldn't be the first time I was wrong though, glad to hear your up and running lester622.
One side note, since that mod is for a remote start a person needs to be careful if/when labeling that switch:
Connect the yellow wires to the switch such that the contacts are OPEN when the switch is in the ON position.....
Going by the directions for labeling that switch, notice that passlock would be OFF when the switch is in the ON position and ON when in the OFF position.
