Hey all,
Has anyone ever installed a push button ignition kit into their Rex? I'm thinking of doing it, and wiring is my specialty, but if anyone has, exactly what does the wiring instructions entail? I've tried various websites that sell the products, but their .pdf instructions weren't very clear and detailed. Just general. :P

I've never installed one, but isn't it just a momentary type switch that gets hooked up to the cranking wire. So I guess with a test light or meter look for the wire that shows voltage when engine is cranking from the ignition switch and hook that up to the new switch.

I was thinking of doing my own with one of these switches.


Or get one from an s2000 cause I don't like the ignited ones.

Actually all the websites I went to showcase the Ignited Performance Original Push Button Ignition kit, the same one that's found in the S2000. I saw it, and liked it. They had the general instructions, so I knew of the idea of power, ground, power for the lighted up button, etc, but it was very general in what to hook it up to. I guess that's the best one could get, but I figured if someone DID do it, then they'd know exactly what gauge wire is to be connected to what. Save me a lot of guess work.

U got it
I cant say i have done in in a 7 but i put one in my Dad's truck. he got some pissed off cause he was afraid it would make it too easy to steal. thats besides the point though.

The first gen rx-7 have some really shitty wiring. find a decent wiring diagram and track down all the wires u need. I just so happen to have some pics of the wires u need to find. ill post in a sec. i need to find my camera cable.

Well the kit boasts that you need the key to start it, but I was also planning on sticking in a Kill Switch, hidden of course, to keep it from being able to move. Also, I've seen some of the shitty wiring located in the steering column. Looks a lot neater than my old truck. Plus, as I've said, wiring's my specialty so I love a challenge. ^^ I have the Haynes manual with the wiring diagram but I'll always except more photos.

Well i have no idea which one does what... but in assuming u could get a multi meter on there and figure out real quick.

Blue wire is probably the one u want. There is also the black wires with the white and yellow stripes. There is a red and black probably just positive and negative that are always on. There is also the wire that cause the buzzing when ever the key is left in. lol u gotta sort it out.

Thought the pics might give u an idea of what ur up against
u may even want to rewire parts of your ignition circiut seeing as ur a wiring guru.

Sorry for the double post but isnt the whole point of a button ignition to make it keyless? lol

Kill switch is a great idea. hide it somewhere so that u have to turn it on before u can start the car.

The wiring for the ignition is in pretty plain view. once thw cover it off.

attack it with your mulimeter

there was a write up about his very subject about a week or two ago, use the search function, it was outlined as to exactly which wires & what to watch out for.

Yup, when I broke my steering column, I saw those wires. A LOT cleaner than my truck's steering column jumbled mess.

And, yeah I believe there is a way to make the kit entirely keyless. Just have to probably add in a few more switches like they do in race cars, what with all those toggle switches.

Here's a cool write up on installing an s2000 engine start button on a Miata.

Same concept, he installed his where the cigarrete lighter was. The original Honda one is not the same as the cheap ignited one. Honda S2000 Starter Button Install on Miata

Thanks for the help. I've tried the search function but the results actually didn't help much at all. I'll just go by the general diagram that Ignited Performance gives along with what Kim's FB did with the Miata install. I think I can go from there, along with a multi-meter.

First link I read before but found it inadequate.
2nd link is useless, doesn't entail the installation of said kit. Just talks about additional modifications.
3rd link was helpful on the second page on what wires he was using. That is what I was wanting that none of my search results provided. The wires to use. That's it.

I also like to keep my search results to ONLY 1st Gen Specific, alot of the results I pulled up were 2nd and 3rd Gen. That's not what I own, so why make it complicated?

theres a guy on here that did it, i think his name is "BLOWNandTWISTED", let me track it down and you can shoot him a PM

EDIT: https://www.rx7club.com/1st-generation-specific-1979-1985-18/start-up-video-510751/ theres his thread i was right on the name. check out the video he made of his car, http://media.putfile.com/RMOV2


make sure to post how it goes, take tuns of pictures

Looks like he has the same "Add Coolant" idiot light problem like a lot of us do. And, yeah I'll post pictures as I go along, what the hell. Tho, I'll just use the location of the cigarette lighter for the button instead of the center joystick. I'll probably replace the stereo joystick with a black plate or something. Thanks.

As for the wire colours, they change, follow them down under the dash, and they will be plugged into another harness, the wire colours I referred to are really the ones in the main harness, not the combo switch harness.

Duuuuude, your original post was the one I found helpful with the colors! I'm planning on using Ignited Performance's "Original Push Button Ignition" kit. Hopefully, I'll still be able to install it, now that you mentioned which two main wires to be using. Awesome, thanks a lot. And, you recommended a 30 amp relay, right?

One more thing, your page says an S4 alternator. I'm clueless, what car alternator would I ask for if going to a parts store?

P.S. - Hey, I gotta say, when I saw how you made that Power Rotor icon, I f'in laughed. That's awesome.

lol, thanks

The S4 alternator is a series 4 RX-7, the earlier 2nd gens. However, theres the GM alternator that some people are using now with way more amperage, I think the thread got archived. You should look into that one.

And yea, a 30 amp relay should be enough.

What in that tread did you not find useful! Everything is there. I did this in the racecar about 3 weeks ago. There is a black and yellow wire that goes to the switch. Splice that wire to your starter switch...12V to the other side of your switch and bam..you have a push button start.

Now- your going to have to fire up the coils and distributor. For this. I suggest taking another switch...Maybe a master...wiring 12 volts to that. Then take the 12V switched to the + side of the coil and bridge the second coil. That will fire up your electrical system and the push botton will start your car.

What I said was that some of the results *I* pulled up were not helpful. By that, they were not specific enough. I need information, I like it to be as detailed as possible. Those posts were just that they did it and a vague statement of what (like ignition to switch, not this color wire to switch). Darkfrost's post was the one that was dead on specific with the colors and how to do it correctly. That's all that I needed.
