Push Button Start with Passive Device Key wanted

This is based off of Chevy Color Code but as long as you can identify the different wires from your original ignition switch this is how to set it up. Remeber that this will turn the car on when you walk up to it so there is no way to turn it off with out walking away from the car. This could be potentially hazardous if something happens and you need to turn the car off. If you want, you can put an SPST switch on the ground coming from the RFID relay that you normally keep on but it can be switched off in the event that you need to kill the car. It can be a small microswitch since it wont be carrying any heavy current through it. Basic function of this setup is as follws, The RFID relay is a switch that triggers the POWER RELAY and the START RELAY. The POWER RELAY powers up the IGNITON and ACCESSORY circuits only. The START RELAY handles the STARTER and the ground trigger is handled by a momentary switch of your choice. This can be an S2000 start button, Z8 button ect. This does not have provisions to light up the button however it could be setup if you splice off of the IGN or ACC wires and hook it to the light. This will keep the light lit when the car is turned on and could indicate that those circuits are hot. With a latching relay you could hook it up so that the light is on until the STARTER is engaged and then it turns off after you pressed the button. This is expensive though and wont keep the STARTER from being engaged a second time so its purely esthetic. This should handle what you are asking for though and is pretty simple in its operation. Hope that helps

PS the 20 amp fuse for the starter is just a recommendation, based off of how much current the starter solenoid draws it may need to be bigger but as it is, it is fused at the same size that most cars are for the starter and it should work fine.
