    I'd like to convert my top cigarette lighter (there are two more below it) to a momentary switch to start the engine, while having the key in not be able to start the engine. This will work as a kill switch since the starting switch will be incognito.

    I've already researched this and found others that have done this with other vehicles, so I know how to convert the cigarette lighter over to a switch, and I have a plan for adding in a 3 position switch so I can easily revert back to the stock method (with the key) in case I need to drop it off at the mechanic.

    My main need is a wiring diagram for a 2000 3RZ 4x4 auto or some help locating the wire that leaves the ignition switch and goes to the starter. This is the wire that I'm going to cut to add in my own switch.

    Also, can I assume that the wire from the ignition switch to the starter relay has no other lock-out devices like the trans Park / Neutral switch? If not, then this project will be super easy and cost less than $10!

    Your wire goes through the7.5 amp start fuse the neutral safety switch to energize the coil of the starter relay

    I think you are looking for power source diagram:

    and/or Starting

    Ignore the yelow and green wire going to the right, thy are for clutch cancel switch.

    Perfect!
    And that black wire I need in the diagram confirms what I've seen elsewhere but couldn't confirm it was relevant to my truck.

    If I am reading the 2 above posts correctly, when the key is turned all the way to the start position, power goes from the ignition switch to a 7.5amp fuse. That's where I'd like to add my own connections. According to this, I can find that fuse in the fuse panel in the lower left of the dash. Seems pretty easy.

    Hey guys, sorry to resurrect an old thread but y’all seem like you know what you’re talking about… And I am having trouble installing a push button start in my 2000 taco V6 4 x 4. I’ve got everything wired up the way it’s supposed to be wired up, according to diagrams that came with the push button and the wiring schematics, I’ve found for my truck The problem is when I push the button it just cranks and cranks and never starts if I take the push button out however, and plug everything back in it starts just fine. The one thing I@keep thinking about is the white wire with red stripe that comes off of the ignition tumbler. That wire did not get anything hooked up to it and when I tested it is a constant 12 V. Should I be hooking something up to that wire from my push button harness that will give the truck spark or whatever it needs to start with the push button? Thanks in advance. .

    Without the print to your new push button switch no idea what your missing.

    It sure sounds like your missing the Brown/Red stripe wire to the ignition coils no way will it start without the ignition being energized.

    This push button is made to just crank the engine?? Why did you add this switch??

    What controls the rest of the ignition switch functions ??

    Does the push button also pull in a latching relay to energize the ignition? What shuts off the engine ??

    AM2 energizes the ignition system without that being done in some fashion it will never start.

    Best of Luck!

    @Bivouac, thank you. I’ll try to explain it simply. I attach an TFID chip to my keys and drop my keys in the cup holder (where I hid the RFID reader), that unlocks the system. At that point if I don’t step on the brake, and I just push the button once, that puts me in the ACC position and I can use my radio HVAC etc. I push the button again and it exits ACC mode. If I step on the brake, the button lights up, then I long press the button and the truck is supposed to start, but it just cranks, no start. The button comes with a wiring harness that has several wires, one for each of the 6 that make up my factory ignition plug under the column, a ground, and one that goes to my brake light switch a the brake pedal. The kit is such that the only wire that doesn’t get something hooked to it in then factory ignition plug under the column EXCEPT for the white wire with a red stripe, nothing hooks to that. That being said, I don’t believe I ever saw a black wire with ma brown stripe. Where can I find that one and what need to hook to it? I’ll find the instructions online and share them here so you can see what I’m talking about.

    If your truck has the stock 2000 wiring harness The black/red stripe should be attached to pin 6 of the ignition switch then goes to the ignition coil harness that attaches to pin 1 of all the coils.

    For what ever reason you have not upgraded to a chipped key not having that in the circuit could cause a no run problem.

    i need to look at your schematic which was not shown. It seems this should be plug and play and plug into your ignition harness . Look at pin 6 and pin 7 at either of those places you have a poor connection pin 7 would be the White /red stripe and pin 6 the brown /red stripe on the truck harness .

    The only other thing some place in this push button start has an open circuit .

    Unless you were rather rough disconnecting the ignition switch and broke something .( we all make mistakes) This product is not working send it back.

    If I was to do this I would use all Toyota Parts and make it work.

    Things are expensive but to trust starting to a $24.00 after market kit good luck.

    Electrical problems can be time consuming to trouble shoot.

    Are you saying that I should have a chipped key? I’ve never had one and I actually had to put a new tumbler in recently. I’m using the keys that came with that part. It’s kinda an interesting Tacoma though from I’ve been told. It’s a V6 4x4 SR5, but it doesn’t have ABS, no rear diff lock, and manual door locks & windows. Maybe not so uncommon, but I’ve had some shops tell me it’s odd. Was a chipped key an option that maybe was left off of this pickup for whatever reason? Anyways I’m gonna go look at my ignition harness and I’ll tell you exactly what I have and what wires from the Push Button I’ve connected where. As far as I can tell it is in fact the stock factory harness. Thanks for your input man, greatly appreciated.

    The only way you would have a chipped key was if it had been added .

    That was not an option back in 2000 .

    Good luck.

    Okay, If you have a minute, could you look at the pic I uploaded, and maybe tell me what wore on the left side (push button) goes to which wore on the right side (truck ignition). I thought I had it correct but clearly there’s something not right. May your expertise will hold the solution I need . Thanks again for your help.

    Really hard without knowing the pin out on the push button plug. .

    It is just plug and play or must you wire the plug yourself ??

    You never thought to test things before installing ?

    I still say it does not work like it should . Send it back try again unless you feel you broke things some how.

    Your truck side pin 6 should have constant system voltage as soon as the process starts if it does not it will crank but never start. Then it needs to stay energized till the engine is shut off. It seems nothing reaches that pin .

    it can be almost anything something is open and not working.

    The pic out on the push button plug is the list on the left, the list on the right is the Taco ignition as you know. Pin 6 on the truck does have constant 12v, and yes I stuck my multi meter on each on before I started. But zi also Googled like mad looking for someone that had already done this and I thought I’d found that so I copied him And there’s just something slightly off. What does AM1, AM2, and ST1 stand for on the truck ignition harness?

    Important **** If the truck starts and runs in the stock configuration !!!

    Your Push Button switch does not work.

    This is not several hundred dollars worth of electronics .


    AM2 is the part of the ignition switch that cranks the engine.

    AM1 is all the other functions along with also being closed while cranking or the engine would not start

    ST1 is the number 1 pin on the ignition switch.

    Remember all the plug numbers are shown with the plug front facing you.
