Push button, start button or switch wiring

[Spanky37]

I want to be able to wire a start button, a switch for that button, and then a switch for my acc. there are 5 wires on the back of my ignition white/red(12v power) black/yellow(for starter) black/white(windows, locks) black/green(also for starting) and blue(acc) the button i have is a 15 amp button and the switch i have to go to the button is one of those racing switches that has a cover on it to where you close it and it turns the switch off. and going to get another switch for my accessories. now i want to see if this set up would work.

1. cut the 2 wires for the starter black/yellow and black/green 2. take the ends of those 2 wires that go to the starter (not the ignition side), and connect them. 3. take my 10 gauge wire and extend that wire which was made of the 2 wires from the starter into 1. connect the extended wire to one side of the button. then run a wire from the other side of the button to one side of the toggle switch. then run a wire from the other side of the switch to ground for power.

4. now cut the blue wire which is your accessories and connect one side of that to a toggle switch and then the other side to the other end of the toggle switch basically creating a bridge with the switch into the wire. and of course you will be extending that to wherever you want your switch to go.

if this would work it would only work with your key in the "ON" position . ..

but i do not want to cut anything til i know this would work.... it sounds like it will but this is why i am posting this... my only concerns are is the amperage from the battery, which i have read to be 30 amps, going to be too much for the start button .. i have read that people use a relay. if so where in my wiring would this go?elp

i want to be able to have a start button and a start switch in other words the switch would activate the button and would have to have the key in the "ON" position and start the car. on the back of the ignition cylinder there are 5 wires (white/red)(12v power), (black/yellow)(starter), (black/green)(one of the acc) (black)(not sure), and blue which im also not sure which that one does. what i want to know is which wires i cut to have the button and switch in a bridge with.. i tried it with the 12v and the starter with the key to the on position and it would just act like it would start . so theres got to be another wire that has to be connected with unless i did it wrong. can anybody help

I can start by applying 12v directly to starter. anyway, there are two wires that get power. the two wires that dont have power when ignition is on position.

[Spanky37]

so r u saying that i should bridge the starter the 12v and the other wire that isnt on when the key is in the on position?

When you turn key to start position, power goes to black/green and black/yellow but these wire colours change at the harness. the other thing is that power stops going to accessories when you turn key to start. for this reason, you should probably forget the start button idea. the reason my car starts when i just give power to starter wire is probably because power goes down line to black/green which goes to ecu. unless you figure out away to turn off accessory while pushing button , you will have a less than optimal start.

theres a way to do it trust me.. ive seen a couple with them in there.. i just got to figure out which ones to bridge

I dont know what you mean. You can obviously just connect the last two wires to the button and it will start but it wont be as good as starting with the switch. The switch is turning off power to accessories when you are momentarily in start mode. Lets be unambiguous, people who use start buttons are butchers.

Thanks buddy! Oh btw, my brother does this for a living, I'll try to get him on in the morning and see if he'll answer your question. I'm sure it will work out bro.

This is a very easy task, and you should not be worried about turning off the ign circut and acc. circut. The only reason the factory does it is to save power while the battery starts the car. To do it correctly you will need two switches. 1 to turn on acc power to vehicle and another to turn on ign power to car. A honda s2000 push button fits perfectly into the factory 240sx key cylinder spot. If you are confused on how to do the switches let me know but everything should be wired up with a relay. O and 240's use 2 starter wires so both will need power for cold starts.

Here is a picture to show how it looks. Please note that if you put a push button in your car your going to want to hide your ign switches so it isnt easy as pie to steal your car. I have 2 ign kills and a starter kill as well as a master kill switch that kills the whole system.

It has been like this for 4 years with no isses.

the only reason i want a start button is because i can start my car with anything. dont need a key.. there for i need to wire a button and a switch and hide one of them .. see what i mean..

sviellvoicae: you said there are two starter wires? which ones are they i know the black with yellow is one..

This is easy

List of supplies:1-push button starter switch3-100 amp switches1-spool 10ga wire1-spool 14a wire1-pkg male and female spade connectors 10ga1-pkg weatherproof male and female spade connectors 14ga1-round hole connector 14ga

Here goes, disconnect negative battery cable, cut (white/red)(12v power), (black/green)(one of the acc), (black)(ground), use your spade connectors and 10ga wire to "extend" them to wherever you want to hide your switches, i would suggest "etending" them one at a time since your spool of wire will be one color and unless you want to buy 3 spools of diff color wires, it will be easy to mix them up, there we go, switches, check

Push button, wire a female spade to the end of the wire on one side of push button, round on the end of the other, take off your positive battery cable, remove the bolt from your terminal clamp, insert round connector, put bolt back into clamp through your new round connector, replace positive battery cable, take female spade through firewall into engine bay, look at your starter, there will be two bolts and a push on spade connector, remove factory spade connector, replace with yours, push button start, check

you will still need the key to start but you can now disable the ability to start even with the key, vehicle with all switches on will turn on but the key will not crank it, only the button will, turn all switches off, even if they steal your keys, find your push button, car will never turn on unless they find all three switches.

Good info! I'm going to use this for my remote starter setup.

The only thing is I don't like the fact of not using a line fuse. Could fry some stuff there if a short comes your way.

I would think one off of a subwoofer setup would work great

[sviellvoicae]

You need no more than a 25a fuse for a remote start. That sub fuse will be overkill thus being pointless. Also do not go to your starter directly with a remote start... O and when dealing with your ign wire never use butt connectors use solder...

this is good info.. however your colors are off on the wires. there are 5 wires in the back of your ignition white/red(12v power) black/yellow(starter) black/white(goes to your ac and s*** like that) black/green(starter) and blue(electrical or acc)

the way you are explaining it seems like you are cutting the 12v wire and bridging a switch in between it and then doing the same with the starter and the acc. if thats the case with all the switches on you would be able to crank it with your key.

the way i want to crank it is with only 2 switches and a button. 1 switch for both of the starter wires and the button on that circuit and then 1 switch bridging the acc wire. so that i can turn the acc off when starting the car . and the switch for the starter would only be there so that i dont bump the button trying to start the car when it is already started.. the way im explaining i would have to ahve the key in the on position to start it..

the only thing i dont understand is the whole amp part of it and haveing to use a relay cause you cant run so much through the button.

[Spanky37]

anyone?

[rsagen]

the amp part?

I mean like use a line fuse.

Play it smart. If a short happens byby starter.

What are you doing for your remote start setup?

[Spanky37]

i mean the amperage as in how much can i pull throught he button or would it just burn out.. but i bought a relay to reduce that so i think it will all work now.

[sviellvoicae]

What are you doing for your remote start setup?

5901 if he is smart.

A relay is simply a switch. It doenst make less current.

[rsagen]

for the remote starter im not going to run this exact setup, just use the info on the wire colors to wire it myself

[Spanky37]

i updated a more detailed explanation of what i need to do. please re read the first post
