1. Remove steering column cover.
2. Locate the Blue and Black/Yellow wire in key cylinder.
3. Tap the red wire to the blue (acces) wire. (make sure the wire is fused)
4. Cut the black/yellow wire.
5. Tap the black wire to the starter side on the black/yellow wire.
6. Tape off the end of the black/yellow wire (cylinder side).
7. Reinstall the steering column cover.

YOUR DONE!

Cool stuff. Always wanted to know how to do that...

Also, what amperage fuse do you suggest? 20, 25?

It'd depend on wire amp rating, what the rated wattage on the switch is, and how much watts run through the starter wire.

And Klox =) thanks for this, someone should pin it!

No Problem! Go with a 10 or 15 AMP Fuse! You don't want a fuse rating that is too high!!!

Also, if you want to do this on your other vehicles,
http://www.the12volt.com/installbay/vehicles.html
has wiring diagrams for car alarm installs, which has the info for the colors on the ignition switch harness.

reason I post this, i was gonna do it on my corolla as well as my nissan, but the corolla is my test vehicle, so I wanted to do it on it first.

definitely! I did mine at work... its the slow time of the year and i had time to burn! it took me about 10mins to make the bracket to mount the button, and about 15 mins to do the wiring! just remember to have good connections!!! SOLDER!!!!

heh, i removed my cigarette lighter on my corolla and put a round push button in that spot, it actually looks good, it looks like its supposed to be there

Might be a dumb question, and I don't mean to sound negative......but whats the point?  Looks like you still have to turn the key "on" first, before you push the button.....

I would see it as a theft protection, cause most theifs use bump keys and if they turn it and it isn't starting, they go WTF, this is a POS and leave..

The button just has to be digusied or hidden

yup, you turn the key and it just runs down the battery =)

The only thing is, make sure you get a good quality button, otherwise you'll be dealing with a lot of shorting out when you try to start it.

Has anyone played with an immobilizer? Like an RFID key system where you just hop in the car, chip on a keychain closes the starter ciruit then push button start?

It would be realllllyyy cool.

Well today i went to autozone and picked a $10 push button..i wired it directley to the starter and tthe other conection to the signal wire wire...it works fine !
But the question is did i do anything wrong???

David BMay 15, 2008, 6:42 pm · #14

well, you said directly to the starteR?
why not just to the wires by the steering wheel?

mine worked for a day and killed my starter, but you saw my video so i guess you get it.

post a pic of your button

speedracerMay 15, 2008, 7:33 pm · #15

well im not on my pc but it is just a temporary push botton with rubber suround...

David BMay 15, 2008, 7:48 pm · #16

then you should be fine?
as long as your connections are solid.
and as long as your car starts, your in the green

Awe... i remember when i posted this thread... good times... i adventually took out the push button, cuz it was driving me crazy... cuz in the early mornings and late nights... i would for get i had it!!! lol...

well later i had a problem with the wire that went from the key to the starter... so i hooker it up again.. cuz i was too lazy to see what was wrong wit it.. only this time, i used 12v from teh battery, and a wire straight from the battery... more reliable than the 20 plus year old ign. wires!!!

Good tutorial. Helped me alot, and not that difficult. though i would suggest an inline tap tha tyou can get at walmart for like 20 cents. I wired the button next to my e-brake  though i accidently broke the panel i placed the switch and button in so i need to find another one at the junkyard...

sideways_s12Nov 23, 2010, 2:26 pm · #19

So I can go straight from the starter to the button? And ground the wire from the otherside of the button

Hey you still need the key to use the push t start best way is t take the drum where the key goes and take it to a. Locksmith
