look under the dash for the data plug, remove the two screws and drop the plug done...look on the plug for the numbers....you need to take a jumper wire from pins 4 and 8 and jump them together. when you do that, the door locks will respond by locking and the rear window will pop open....at that time, press both the lock and unlock buttons on a transmitter....the locks will respond...then do the second transmitter the same way.......when your done remove the jumper and test the transmitter....that should do it for ya!
