I dont think that is what he was talking about. I belive there was a tread in either this section or the race section. check the bottom of the page.

Nick - What're you talking about? The links I gave all relate to push button start.

lol this has to be the easiest mod ever lol! Remove signal wire from solenoid attach to 100amp push button attach wire from 100 amp button back to starter lol! add a relay if yah want

simple push button take a button thats intermediate which means for push operation take the signal wire off you starter and run a new wire from the contact to the button then run the another wire to a constant hot. boom push button start but you'll still need the ignition key on, this is good for theft deter ant they wont be able to start the car by forcing the lock.

wow its like a newb echo in here. This is really one of those questions that if you have to ask sell your car before you blow it up! Man_in_black49464 that was not a stab at you in anyway

I would like to do remote start in my '82, but its not enough to just turn the key - I need to be in the car to work the throttle to get her started

it depends what you want it to do. If you want it to operate like the ign cyl does, then two high amp relays would be needed. Also, if you use relays, you gain the ability to use a lower amp switch. (the s2000 start button for example)

Dude you picked one of the most remedial questions to ask! Seriously if you do not know how a starter works or is wired to figure this out you probably should not touch it.

No offense, but you are kind of being a dick. Everyone didn't know how a starter worked at one point, and then they learned.

A basic switch on the starter is a very simple procedure. I don't think this is the best way to go about it. First, a push start button is usually near the steering column, and it makes sense to make use of the ignition wiring that is already there, instead of running new wire up from the floorboards.

Secondly, most high current switches are both ugly and expensive. The mod is much more attractive using a low current switch, like the s2000 start button (which fits in the cig lighter cutout) or some generic ebay start button. To facilitate the higher current demanded by the starter, a simple automotive relay can be used.

If you notice when you start your car, your accessories and headlights cut out while the car is starting. The idea behind this is that all the unnecessary draw is taken off the electrical system to give the starter the best chance of starting the car, especially in the cold. This same operation can be maintained using an additional relay (or possibly two, haven't looked at the rx wiring, for a miata only one was needed).

I think those links posted in the second post should get you what you want.

i know how a starter works and with the 3 rx7's ive owned in the past ive never considered using a push button starter until now. and also considering this is the first FB ive owned i figured id just ask.

so yetterben quick being a dick

Quick question, since the black/yellow wire controls the signal, could you use just the button between that wire and the starter to engage it? Or is a relay mandatory? I don't mind getting a relay and wiring it up, but I have a switch handy right now.

If you are keeping the rest of the ign column thing intact, you should be able to just reroute that wire to a push button vs the spring loaded roational switch.

No?

That is what I am thinking. Turns out I don't want to be able to still use the key to start. I want it to be pure button, so looks like I am to get a relay.

Oh. And I will be using the cigarette lighter to start it. Who would push it in to start it? I already have it all in my head on how to configure it.

djessence

mmm that could be vera nice. Although be careful with the "auto hold in" thinger in the lighter. Would be very stealth though. I like your thinking.

Sgt Fox

Depends on the current rating on the switch. That wire is at least 10 AWG if I remember, so most switches wouldn't handle the current. I would use a relay.

yetterben

rudimentary 'nuff said. Sorry i stepped on your toes :P

Sgt Fox

cig lighter may not trip the relay due to the resistance in the lighter coils. You could modify a lighter to have less resistance by replacing the coils with a wire though.

My cig lighter sucks, I have to hold it in to charge it. That in itself take 5 minutes to even turn red. I will just unhook the power from there to avoid any heat issues. If I care, I can use that as a signal wire since it comes on with the accessories click on the ignition. Wire that badboy to a small button, grind down the cig lighter end, and just push to go

i fitted a nice starter motor kit, fitted straight into the hole for the choke

edit i ment starter button kit!

I won't be using my cigarette lighter anymore. Well, come to think of it I never used it. It works, but takes forever. I also have to hold it since it never seems to stay down until hot. Looks like a win win. Just need to find a button/relay.
