I posted this mod in my progress thread but I figured I should post it in a new thread so it can be added to the DIY thread if it is worthy enough.

DISCLAIMER:

This engine start button is in ADDITION to your turn-key ignition. As long as you tap the wires, there will be no changes to your existing wiring. THIS IS NOT KEYLESS IGNITION. You will still need to put in the key and turn it to the ON position. THIS MOD IS FOR COOL FACTOR ONLY. IT IS NOT A REAL KEYLESS IGNITION.


Here is the wiring diagram:




Parts list:

Engine start button: Part number 35881-S2A-911
30-amp Relay: here
16-18 gauge wire
20-22 gauge wire
heatshrink (various sizes) and heat gun


The install is pretty straight forward. Feel free to ask any questions. I will answer to the best of my ability.


Here are a couple videos to show it really works:





Happy Modding

 

Where are you going to mount the switch?

 

no idea. haha.

any suggestions?

i want to keep my cig lighter outlet though. i need it for my Nav and phone charger and stuff.

 

nice, i remember buying all the stuff for this mod, but never getting around to doing it.

 

Awesome. I'll do this the next break I get. I would love to have the cigarette lighter be the start button. I don't think I have ever used it anyway.

 

I'd drill a hole somewhere and mount it flush.

Maybe there; by the climate control? I forgot whats behind there. Something important I'm sure...

Id like it down by the shifter somewhere, but I don't think there's enough space.

 

I have a navi, so mine may be a bit different. Either way, that's a great spot to put it.

 

I read that the power connector from a PC floppy drive will hook up to the back of the s2000 switch, acting like a pigtail. Should make wiring a little easier.

 

Nice job, man - I see the front seat sitting there in the garage - hopefully you'll sort that out soon!

This might be a dumb suggestion, but you can put the Engine Start button where the cup holders are - it'll just be cool to see the panels open and reveal the button before you press it. But then again, you might accidentally start/turn off the engine when you're using the cup-holders...

But yeah, by the climate control would be perfect

 

Thats awesome man. But i think ill wait till we find a way to start it without the key before i attempt this mod. But ill give you props man.

 

yeah there is one other person i know of with the S2K starter button on his 2nd gen and that is where he put it, in the empty space next to the climate control. who knows, i might end up putting it there as well.


as far as keyless start goes, i encourage anyone who is electronically inclined to tackle retrofitting the Lexus Keyless ignition button.

but the S2K button is just so much easier. it only took me about 45 min, and thats because i had to find the starter (black/white) wire myself. i couldnt find it in the ignition harness or anywhere in the steering column. so i had to look in the fuse box.

 

Damn! I was thinking to do something like this just a couple of days ago, but didnt know wich car actually used a Push Start Button from Honda! Im SO going to do this! PICS of WORK DONE ASAP PLEASE!!

 

Nice mod

 

the 2nd gen TLs have an immobilizer chip in the key right?
if so, a keyless ignition button will never work.

I saw an RFID keyless system on youtube...

 

S2k's themselves are the same way with not actually having a keyless ignition. Still have to have the key turned before you can push the start button. At least if I remember right. Nice small mod though and good write up.

 

no key turning for me.

 

isn't there another lighter socket in the center arm rest box?

 

nice job on the starter. sucks that you have to put the key in

 

yeah there is another socket in the center console, but the one on the center stack is just so much more convenient for plugging in things like a Nav or Radar detector.


for the S2000, does anyone know if you HAVE to use the button to start the car? or can you still turn the key to start the car? if youre forced to use the button, i think in that respect this mod is better you still get to keep both options.

 

Arent the same wire you connected to the s2k switch used on the regular ignition switch? Is there anyway you could reprogram the s2k key to the TL? If so youldnt you be able to use the s2k as the sensor? Im just throwing stuff out here.

 

Yea I'm pretty sure you have to use the button on the s2k.

 

from the videos on youtube it looks like you have to put the key in and push the button even on the s2000

 

Can anyone confirm is the car is still able to be started via the regular key ignition? It would make more sense if you were forced to use the button.

Another idea is to add a simple $4 kill switch. This adds some security/functionality.

Also, do you think I could install the button with just a drill? Would I need to buy a dremel? How much do you think someone would charge to have this installed?

 

With the way I have wired it, you have the option to still use the key to start the car. You do not need to use the starter button every time.

You can install the button if you have like a 3/4" drill. The button is around 3/4" to 1" in diameter.

 

Where can i get a kill switch at? and in stalled?

 

You can buy a kill switch at any electronics store. It's just a simple on/off switch that you connect to the neg wire. It basically just disconnects/completes the circuit.

 

Do i connected to the neg. wire on the ignition? or where?

 

neg. wires usually go to a ground.

 

Haha as you can tell im not an electrical guy. haha

 

hey i wasnt either. but i practiced and spent some time on wikipedia and figured wiring out.

i also had to take an electronics course for my Mechanical Engineering degree but i found wikipedia more useful

 

To use the kill switch, just cut the neg wire and attach both ends to the switch. That way, it's just a simple way to connect and disconnect one cut wire.

 

is there a DIY for it. Because if there is i could go off that.

 

you have to use the button to start the s2k. i have one

 

Hey guy if you look though the old thread I did the s2k button it is not to hard and it give the tl a sporty look inside seach s2k button and you will see my car with it

 

^ yup

it looks like i may put the starter button in the same place you did.

 

Ugh, it looks like I'll have to find a different place to put the button. With the navi model, there's not enough room at that location =[.

 

^ cig lighter? or maybe drivers side door panel. that would be interesting.

or maybe this: here

 

just ordered the push button. as soon as it comes in i'll post a write up

 

it would be funny if someone had that shift knob and was racing and had there car in tiptronic and accidentally presses the button and turns offf the car

 

Haha, they thought ahead and put a cap/cover on the button. Still, I don't know how you would hide the wiring.
