97 Lexus ES300 locks

Hi there. I am installing a remote starter w/pager into this car. i had trouble finding the correct wires as you have to turn the key in the pass. door to test the wires. well after hours of testing the locks seemed to quit working altogether. i hear a small buzzing sound instead of the door locks working.(no batt isnt dead) may be a burnt switch or something as all the fuses seem good. has anyone ran into this problem? ii have looked at diagrams from different sites and it seems there are different locations and colors for the correct lock and unlock, it isnt clear as to the type of lock system it is either. is it 3 wire pos or what? any help will be greatly appreciated, thanks...chip

i did one not too long ago it's straight negative to the following: LOCK|dk. blue/white   |- |org plug bottom of fusebox UNLOCK|dk. blue       |- |org plug bottom of fusebox

great neg trigger than cool. now i gotta figure out what happened to the factory locks now, any ideas? lol bad switch, bad module? i hope i dont have to have a tech repair it:(
