Gee I hope u have not taken the car for a drive yet 'cos u will be real disappointed. Check light 16 refers to the knock sensors - which means the the ecu will have reacted and retarded the ignition lots - the car will run like a dog. Most likely cause will be loose plug on one of the knock sensors. There are 2 of them and they are located under the inlet manifold.
Unless u have also swapped over the speedo U will also have a check light 42 when u get the beast on the road. This is easy to get around just use a cruise control pickup on the tailshaft. A 42 appears if the engine runs for 3,000 rpm for longer than 20 secs while stationary!
