Push Button Start

[fourgsixthree33]

First off, I have done tons of searching. From the information I have found, I was able to build a diagram (picture attached) using a standard automotive relay. I have specific questions about how I want mine ran.

-I don't want to use the key; at all. I will be completely removing the key assembly/lock.
-I want ONE toggle switch. The switch will act as if the key was in the ON position (ACC & ON) so that I can flash my ECU with key ON (key ON as in toggle switch ON).

So essentially, I flip ON the toggle switch, everything gets power (heater, radio, windows, everything), and then I start the car by use of the push button.

Now, with all of that being said, please take a look at my diagram and note the information above the push button start panel (Power From Ignition Switch).

Do I need to do that? Knowing my intentions with everything I wrote above. Can I just run the wire from pin 86 to the push button and not go past that on pin 86? Since I am using ONE toggle, wouldnt the toggle switch have a wire from the toggle to the power wire from the ignition switch?

Hell, Do I even need a relay at all going this route? After reading on other threads, I am lead to believe that a diagram like I had made would only be used if the individual was only using a push button and no toggle switch. Am I right?

EDIT: This is for a 1G btw.

I like your idea!!

Thanks, just hope I can get a little more insight on this whole thing. Completely building a 1G from the ground up and hoping to fire her up soon.

IMHO, you will want to use 3, 30 amp SPDT relays. 1 for acc, 1 for ign and 1 for starter. Then just have a switch able to handle 5-10 amps, 12v from switch to pin 86, ground on pin 85 (you can swap these as you see fit) on the acc and ign relays, inputs from each going to respective 87 terminals, 30 terminal is the output side away from original switch.
Starter solenoid, T off the ignition after its relay (output/30 side), going to pin 86, ground pin 85, starter wire cut with push button on 87 terminal, output to solenoid on 30.

I'd draw a diagram, but I'm on my phone, on the crapper. Ha

Lol. I appreciate the response. I am far from a wiring expert so it might take me a bit to put all of your advice together into a diagram. That's a lot of stuff haha. But thanks! I will do my best with what you have said.

Any update on this? Been a few years.

Without really diving into it too far, the obvious thing to do would be to just unplug the keyed ignition switch, and wire the new switches in right at that plug. That would keep most of the stock wiring(like the clutch/neutral interlock that prevents you from starting it unless the clutch is in, still functional.

FWIW, there are kits on ebay for $20-$30 that include a push button start switch, with small RFID keys, and a control unit. That might be a way to do what you want, without trying to figure out all of the wiring yourself.
