does any1 have the schematics for the vats system. Mine is a mess and i want to see what the hell is gooing on

 

You didn' say what car you are working with.
However, this link shows the diagram for a 94 Camaro, http://shbox.com/1/pass_key.jpg
Most GM cars using VATS follow the same layout. Keep in mind that the car will not work without the VATS module unless the PCM is reprogrammed or extensive rewiring performed. The key, and the key contacts can be bypassed by strapping a proper value resitor to the 2 wires going to the VATS module, but the module has to be kept active. When the VATS module sees the proper resistance from the key, it sends a coded digital signal to the PCM. When the PCM sees the signal, itenables the fuel injectorsand power to the starter relay.

 

thanks alot it is a 92 and somebody really messed with the vats i need to trace all the wires do u have any links for the rest of the anti theft
