I just got myself a 95 Z28 project car, its in really good shape but with the keyless system the door lock butten dosnt work, it works fine on the hatch and door unlock, are there any relays that control lock - unlock, and where is the module located ? thanx

 

its located on the passenger side, below the dash, underneath the left side kick panel. its the black box with i think 2 sets of wires going to it.

 

should be bigger than the vats black box. The vats has less wire too.
