Chemical. You are asking for the installation instruction instead of definition of what it is right? Well, the installation of the timer is all done inside the cabin of your car at the steering column. In the nut shell, when you turn the car off and removed the key the car should be running for a few minutes, so you have to find the exact wirings for the power source and relays using the electrical schematic which you can get one from parts dept @ Honda. If I remember correctly you would be looking for the power, fuel pump, and ecu wirings. By pass those wirings with those from the timer should do the trick. It is not easy like it seems. I have done this on the Supra Turbo before but not yet on the S2K. So good luck chemical.
