Don't kill me for coming back and digging up a half-dead thread...but.. I've been gone for awhile, and have some info for the push button start.

For starters, I never got around to completing the project since my Q (^^^pictured above^^^) got totaled and I broke the second Q. Yet, I acquired all the parts and most of the specs, but still unsure if it would work due to the Q45's complex security system. (how many of us have spent hours trying to start your car, only to realize the security lockout had engaged, and all you had to do was open the trunk with the key...)
Secondly, It is important to say that you should use Quality parts in this process. The start button (pictured^^) is a real Honda S2000 start button which I purchased from the local Honda dealership parts department. Don't get the cheapo "Big Red Button" that is all over eBay and has even trickled into the auto parts stores. You will also need at least one relay. I purchased one from Parts Express (

Also, the socket at the back of the Honda starter button is the perfect size and fit for a floppy-drive computer cable connector. Sounds weird, I know. So find one of your old 3.5 inch floppy power cable and chop it off with a few inches of wire left on the connector. Lastly, you're gonna need lots of wire (a few various colors will help) and a good assortment of connectors.
Next is the research phase. As you know, my other car is a Miata, and many members of Miata.net are successfully installing these in old and new Miatas. So if you're serious about doing this, head on over to these Miata.net pages and read the complete write-ups and look at the wiring diagrams. Obviously this isn't what the Q ignition cylinder and wires are going to look like, but anything helps when doing this from scratch.

here's an example of the Big Red Button not to use, but the write-up might help to familiarize things a bit more:3.)

After getting the parts and doing the prior research, I began researching how to adapt the diagrams over to the Q. Good news is, Infiniti was kind enough to include amazing technical manuals in the Q45's. So I got out the wiring diagram and poured over it for days and days.....
And I'm very sorry to report, my friends, that is as far as I have gotten. I'm honestly not sure if the crazy Q45 security lockout would accept the slight modifications... But on the other hand, there is a chance that the system would never know the difference. I promise that when I get another Q, and I will scince I have the NicoECU and strut brace, I will complete the research and installation... final writeup to come someday. Hopefully someone with some more ignition experience with the Q will jump in and pick up where I left off.
Finally, for the S2000 starter button to work, with the relay schematics, you must have the key in the ignition. So it's not going to make the car any less secure. Remember: inserting the key powers the first stage of the system, powering the IGN wires. TURNING the key to start engages the IGN wires.. Without the key in the ignition, pushing the button will do nothing, except possibly engage the security lockout (thus requiring the opening of the trunk with the key, blah blah blah). So if anything, it would be making the car more secure, since some idiot would never be able to get it started. The start button only replace the action of turning-the-key-to-start with the action of pushing-the-button.
More good news: the Honda S2000 start button lights up quite nicely, and fits perfectly in the Hazard button location of the Q45. Now don't just disconnect the Hazard button because then your lights/turn signals won't work. There's enough room behind that dash panel to stuff it back there.
Pros: looks sexy, will gain you cool points with friends / women / office buddies, may theoretically improve security, adds a modern touch to a mid-90's car, lights up and has chrome.
Cons: huge pain in the arse to install, could require partial loss of Hazard function, might not even work with the Q45ignition security, cost about $100 from start to finish.
