one of the programmings that I had done and you might consider, removing those annoying gongs (the dash light for seat belt is still there), getting high beams to work at the same time with the front fogs, lock the doors as you start driving... those are thngs you can do with the sw and the cable... i also synched the car clock to GPS time beacon...
without the cable you can adjust the speed sensitive volume - search for GAL in the forum, there will be instructions... also, if Slick stops by this thread, in his signature line there is a direct link to OBD test functions, such as digital tach, digital speedo, battery voltage, coolant temp... you just press the right knob on the cluster, it will reset your trips to zero, but keep on holding until you see test... Test 2 is nice display show of the cluster... all the other tests call for unlocking the cluster - instructions are on this forum...
