Honda S2000 Style "Engine Start" button

I know a couple of you guys installed one of these nifty little buttons in your cars - I am in the midst of putting one in my V6, but I need a little help.

Anyway, I put the button where my cig lighter once was, got some power connected to it so that the two wires going TO the relay will carry 12V once the button is pressed, but the two wires going FROM the relay and to the ignition barrel apparently carry no power at all. I even replaced the relay provided with a brand new one. There's a click inside both of them whenever the button is pushed. So, they both seem to be working!

Well, the switch going out of the ignition consists of four wires: Black/white, black/blue, red/black and blue. Taking this switch out prevents the car from starting so I obviously need to connect the button to two of those wires!

However, even when turning the key to make the car start, I can't seem to measure any kind of current in any of the four wires, so I made a noobish guess and figured that the button might be alright anyway!

I've heard that the black/white and black/blue wires are the ones I need to connect my button to, but..... no luck thus far.

I need a little help. Where did I f... up?

You sound intelligent, but I think you're either over-doing it or have simply got something messed up..

If you'll look through the wiring diagrams you'll see what you need. Just splice in series from the START position wire.

Depends what you want. Key ON, start button, START still works though... lots of possibilities.

Thanks for the reply. I'll try installing the button the other way around. I'll start with connecting the two wires going to the ignition. I just need a simple: "turn-the-key-to-on-past-the-acc-position-and-then-press-the-start-button". What wire colors would I need to splice into? I guess I can figure the rest out from there :)

By the way, there's a switch next to the one with the four wires. This switch carries two black wires, am I supposed to use one of those?

one goes to starter selonoid and one goes to the power wire of ignition key cylinder (when key is on *ON*)

After having looked through hundreds of posts on this site, it appears to me that the two black wires are both 12V power wires and that the black/blue wire in the other switch is for the starter. Can anyone confirm this?

if you wire it directly to the starter selonoid you wont have to push the clutch to get it started... like i did...

I was looking at this too. Would I attach the start button to the on position on the key to make the starter only work when the key is in the on position

your key needs to be in the on position, or the car doesn't run....

or you need a switch for the on position.

I know but the start will still spin when you press it if its not wired through the on position correct?

I'm not sure. Depends how you do it. Look at the wiring diagrams.

If you just jump the starter in the off position, it WOULD spin the motor, but nothing would happen, as the ON position fires the main relay which charges the white/red wire which provides power to pretty much every component... injectors included.
