If any1 has done this tell me what i need to do!!! im goin to the good 'ol boneyard!

 

You will need to get the power lock solenoid. It will attach to the lock mechanism you already have. It it very easy to install, two bolts and run one wire. You can get a used switch or go for a new one from GM.

 

thanks it works on a negative ground switch right?

 

yep, the case of the solenoid is attached to the negative chassis ground of the car. will be one other wire on the solenoid, attach this to your switch or aftermarket keyless entry system.
