wire a push button start

lets see if I can help.

Question 1: what kind of car are we working on?

Question 2: am I correct? you want to put a key in the Ign. and press a button and the car starts?

Question 3: What Accesories do you want to turn on when you flip your switches?

the more detailed the answers the better we can all help you

Go under the Dash locate the main Wire harnes running up the column this is the ignition harness Locate the Yellow wire this is the main 12v Hot all the time wire. The RED / lt. blue wire is your starter wire.  RED / lt. green is your ignition wire.  gray / YELLOW is the accesory wire.  take 3 relays  line them all the same way with the pins and numbers so you can see them tape the whole pack together using black elect. tape.  Tap the main 12v wire using whatever method you deam best. then hook use this wire and connect it to pins 86 and 87 on all three relays. take the 2 switches wire one end of the switches to a good ground point.  take the first switch and wire the free end to pin 85 on your first relay. we will call this the Ign. relay & switch. wire pin 30 of the Ign Relay to your RED / lt. green wire. now with the second switch do the same thing only connect pin 30 to the gray / YELLOW wire. now when you flip the switches you have Ign. and Acc. wire the Starter button the same way and you should be good to go. remember always test your wires with a DMM. Also let me say that it would be wise to hide your switches because you basicly just hotwired a car for a potintal thief. if he can bust the stearing wheel free he has a free ride. also for a project of this type or any thing even close to it I highly recomend learning how to read a wire sheet and learn how a relay works. both of which can be found on this website. Please if anybody sees somthing wrong with what I just said please chime in it is midnight and im a little inebriated
