Hey guys I want to do a push-button starter switch into my 93 civic. A simple momentary switch & relay is not a problem as I saw plenty of pictures/steps on how to install one of those.
My question is how do I go about it so that I can eliminate the key all together? I want to be able to start the car without the car at all (I know this is a safety issue I'll worry about that later). How do I go about wiring another swicth for acc,ignition to be able to do that. Using the multimeter I found what the 5 wires do in my ignition:

white - 12V constant
yellow - ignition, off when starter is initiated
yellow w/black- ignition, on when starter is initiated
black w/white- starter
white w/black- acc, on with ignition, off when starter is initiated.

 

For ACC use an on/off switch w/relay. IGN. use on/off switch w/relay. and for starter use momentary with relay. If you need more info/help feel free to IM me.

 

you can do it with simple relays. but main problem might be the bigger wires seeing how im not sure how much current goes thru them wires! if the relays can handle that much power flow with no problems

not sure how id do the turn on feature tho.............
at least securly..... you can wire all the relays together so a simple switch would activate them all, but to make it even easier you can always just wire them together and use a big battery relay, they are mainly for dual battery stereo systems to isolate batteries. BUT are made to handle alot of voltage and you can just wire them all up to it...
then just wire up aliteup push button switch for the starter....

your just looking at a HUGE security risk doing this!!!!!!!! tho on a side note if you can hide all the wires WAY back in the dash and make it look factory and also using a alarm with starter kill for that push button switch!

needlessly said... its still a huge security risk! and youll never be able to take it in for work cause if you tell one person your security or activation switch location..... your screwed!
personaly i wouldnt do it....

 

Seems like a pertty good ideal, If you sat down and take the time to plan things out right. A theif is going to attempt to take a car if it has push button or not. I could see this working out if you have a propery wired up car alarm. The push button could be defeated if the alarm is active. And work if the alarm is disarmed. If you have both of theses options done well, your car would be safe, I been toying around with this ideal for awhile but never gotten to install it. The only down fall is that you would have to modd the key cylinder to not lock at all. But what the heck a theif is going to smash it in 2 sec anyways. If you need any help just let me know. What kind of alarm do you have ?

 

steering wheel lock will be bypassed how

 

There seems to be no steering lock in my vic for some reason, which is good in this case.
Also guys don't worry about security. I know there's a inherent risk in doing this, but my car doesn't see public places and when it's in my driveway it's secured in other means, plus I'll incorporate kill switches in all this. I'm gonna check the amperage of the wires today
