Terminal 30: 12v Positive. Come off of the existing cigarette lighter cable. Terminal 85: Ground, As above come off of the existing cigarette lighter cable. Terminal 86: Trigger source. Start Signal from switch (Pin 1). Terminal 87: To Starter Wire (Black/White).

Terminal 86 senses current change, and it allows the power to flow to terminal 87 which is connected to your device, in this case the Starter Motor wire. The relay is getting it's power from terminal 30. On the S2000 button there is a spring clip and a plastic clip. See diagram. The plastic clip needs to be filed off, the "ridges" need to be filed so that they fit snug in the hole where the button is going. In my case the cigarette lighter adaptor

hole. This meant filing down (with the aid of a Dremel, reduces time enormously) to just below the lower ridge, it fit nice and tight that way. The hole itself, enlarge the hole to fit your S2000 button. There's really no way for me to walk you through this step. Just take your time. Make a small change, test fit your button, remove it, and then make another small change. If you make the hole a little too big, you can always wrap a little electrical tape around the button body to make the fit tight again. If you make a mistake with the notching, that's a little harder to fix. Try to line things up straight, notch a little, then test fit. Just take your time. Once you're done and your button is in place, give it a few victory presses. This is a very important part. If your hole is slightly too tight for your button housing, it'll cause the button to bind and not release right away after you press it. This is bad. You want a tight fit, but not too tight. Next you need to wire it up. Take the lower steering cover off, to see the starter wires, the starter on is the thick black and white wire coming out of the plug. I did NOT cut this wire, what I did was to strip away some of the sleeving and solder the wire from the relay (Terminal 87). I then ran it to the relay. Now remove your S2000 button from the newly cut hole and go to your workbench. We have to cut off the plastic around the 5 prongs and solder leads onto the 3 useful prongs. Cut that white plastic off now (a little cutting disk and your Dremel will work great). Now hold the button so that the red end is facing you and the words ENGINE START are right side up. We will refer to the prong on the outside left as "prong 1", the prong next to that as "prong 2", and the middle prong as "prong 3". The other two prongs are not used and should be bent out of the way. Now cut three 27A wires - one for each prong, in three different colors. I'd suggest Black for Ground, Red for +12v, and Blue for Output to relay (Terminal 86). Prong 1 is the output to your relay, prong 2 will receive power, and prong 3 will be grounded. Solder carefully and make sure you don't make a bridge across any of the prongs. When you're done with the solder, isolate each connection with some electrical tape. You might want to also extend the tape to wrap around the body of the button a little to strengthen each lead. You don't want these breaking off. Now crimp a female spade connector to each lead and put the button aside for now.

The other were a lot easier, ACC or Accessory or Ignition Live is connected to the Green/Yellow wire on the wires to the cigarette lighter connector. As for ground, also use the Black wire spade terminal on the cigarette lighter connector. Tape these securely so that they cannot come free from there terminals. That was all it took. Now all i do is switch the car to "ON", when all the dash lights come on, press "engine start"
