Ok guys, I have had my coupe set up with a push to start set up since the day I built it. I figured it was time to show you how I did it. I am currently in the works of taking the majority of the setup apart so I can get pics to go along with the how to. I should have pics up soon but to give you all an idea of how it works, follow me on this. I am using a 91 prelude si steering wheel to start. I then was able isolate the wire that gets a closed signal when pressed. For me, I chose the excel/resume button. I then disconnected the harness that fed from the steering column to the underside of the dash. From there, I unplugged it to use the lead for my own use. I used a negative trigger relay setup. I soldered a wire to one end, (will get pics soon) and grounded it to chassis. The other end went to the 85 terminal on a standard spdt 5 terminal relay. So this is now the trigger. To make it full proof, the power that enables this relay to even work is tapped from the ignition harness but is DE soldered from the main ignition switch to confuse would be thieves from even seeing the starter input wire. I made a test lead and plugged it into one of the accessory ports on the under dash fuse box for power (only when the ignition is on). From there I used this lead to enable the relay to even be functional. I wanted a second fail safe so I ran a wire from the previous said wire (same wire) to the switched circuit pins of the factory cruise control master button on the left side of the dash. So at this point, the old setup would work as long as I had the ignition on. This setup works if the ignition is on and also if only the master cruise button is selected. After all of this and the rest of the connections are made (will post again with pics and more instructions), you will need to put your key in as normal, but when you crank it like usual, nothing happens. You will have to press the master cruise control button on the dash and then the resume button on the steering wheel for engine start. That along with a 3 relay, isolated circuit kill switch will make your car impossible to steal unless they can get a tow truck to take it with the alarm going off and you have woken up yet to intervene. I will get pics up soon along with a more detailed explanation soon.
