DIY: push start button ( wiring diagram)

[J-Ro]

I prefer having the light for the engine start always on because when you turn the key to ON, the interior lights turn off, so if it's dark out, without it being lit, you'd have to poke around for the button :) To each his own though.
The ring around the hazard button I machined out of 6061 aluminum bar stock. After turning, I wet sanded and polished (minus the fingerprints :)) The ring covers up the edges of the hole in the dash, and I also wanted it to have the same trim as the start button to help give it an OEM appearance.

looks good bro...

Wouldn't you only need an SPST? But yeah, drilling holes in the dash is kind of scary :) The result was good, but the consequences of a screw-up are pretty high

lol... that panel coz an arm and a leg once you messed up...any way.. spst for the relay but for the switch on the hazard you need a spdt unless you wanna hold the hazard while blinkin...\


EDIT* i will add some video hows the botton do the work..lol..

I like the idea and everything but why turn the ignition and then push start ? I mean it looks cool, nicer and everything but can you just push the start button without using the ignition ?

Haha, I think everyone asks the "why" question, but I think you anwsered it yourself: "I mean it looks cool, nicer and everything"
Theoretically, you could do it without the key, but you'd have to somehow disable the ECU from doing the code verification in the key and redo the wiring to bypass the ignition cylinder. In any case, if you did that, anybody could get in your car and start the engine, sans key

i'm gonna have to look into doing this on my car....but the one question that i didn't see answered was...can u still turn the key to start it?? or does it work just like the S2K??

yeap, your just adding another path for the voltage to flow though, so both turning the key and pressing the button works.

Is there any way to wire it so as turning the key to start the car doesn't work?

Yeap, just cut the yellow wire. That way the only input is coming from the relay. But I dont recommend it, becuase your button could possible burn out like my first one did.

[J-Ro]

Cut yellow ignition wire = button start, no key start
Splice yellow ignition wire = button start and key start

I think it would be fairly difficult to burn the button if you're using a 30A relay, and provided you're using the OEM S2K start button and not a replica.
I don't like the idea of splicing the ignition wire because it seems to me that if you want to keep the key start, then why add a button in the first place? Go all the way or don't go at all :)

disconnect the wires from the key ignition. Have them only run to the button.

that's what i figured.....

also i thought to just put like a cut off switch to the key ign.....you could leave it off but just in case the push start does fail....then u could just flip the switch and then the key works again....this is possible right???

btw i got the idea from my old stereo system i had a switch that went between the battery and the amp so everytime i got next to a cop i would just flip the switch and no bass...then when he left flip it back and bass comes back on.....same concept i think

cut the yellow wire so the key wont work but only the acc. (II) will work.
and yes, i leave the the ignition wire on incase if the push start will fail.

*if the push start and the ignition wire (yellow wire) will fail, theres one more trick to make the car run, but im not telling the secrete...

dude.. everybody hatin my floor mats... so im not going to say anything to you...

I dont know if its just recommended, but I have the S2000 push button start in my car and I didnt need a relay for it to work.

we recommend to use a relay just for the safe side... unless if you wanna see a buring wires in the future...

[1st HI 06 Si]

I had read some where that the OEM S2000 button had a built in relay. But that could of been wrong information. It would be really easy for me to add it back in now.
