Installing start button on tacoma

Hi peps , I'm looking for some help with wires on 2006 Tacoma ign wires to install a push to start button . Anyone done this or know where I can find the wiring diagram

I think I found what you're looking for on BBB Industries :



Toyota diagrams aren't the easiest to follow. :silly: But I think you're interested in the white/red and green/black wires at the ignition switch, pins 5 and 7. Pin 5 is from the 30A AM2 fuse (for the starter solenoid), and pin 7 goes to the STA relay. As long as the key is on and the trans in park/neutral (or the clutch pedal down), these two wires are all you need to use on your switch.

I think your referring to using the key fob proximity sensor and factory style push to start button? I'm sure it's possible but would likely be a pretty expensive thing to do as you don't just have to replace the ignition switch with the push to start button but you also have to upgrade your key fob module and fob and then getting it wired and programmed is a whole other issue... maybe I'm reading this wrong and you just want to install a button that you push to activate the starter in which case Tyler's directions are correct

Thanks guys , this will do perfect for me . Diagram plus the other info is spot on . Thanks again

No problem!

Hi guys me again lol
Tyler the diagram looked awesome so I printed it to go and finally h the job but it's a no go .
What I have is the engine start kit from eBay . Has small black box with a relay inside , 4 wires . 1 Black just attach to ground . 1 red to attach to power that's alive on second ign acc . Easy thus far . Then 2 Blue wires again easy right ? Attach one to the wires shown in your diagram, white with red strip wire and the other to the green with black strip which goes to the start relay . At this point I have tried everything and not a thing . Tested the start unit with12volts on red and black wires and works great. Relay closes when button is pushed and power then is at the blue wires . I have looked at everything on YouTube on same unit installand they do the same as me but theirs work no problem . So seems I have no choice but to extend one blue wire out through firewall to the STA relay direct . If that don't work then I will have to use another relay I have here and use larger wire straight to the starter . I do a lot of electronics and car have all been so easy but this one got me puzzled lol I just thought I'd update this for you guys and maybe I'm missing something but just can't to seem to find it . Have a great evening guys .

That's disappointing. Going back to what Ben asked, is this a remote start system? Or just a push button start instead of turning the key?

Could you link us to the videos you watched? Just to get a better idea of the system at work. Really, if the key is on and your start box is putting 12V on the grey/blue wire, then the engine should crank. I'd be hesitant to bypass the STA relay, as that's the neutral safety system.

Hi Tyler , I don't mean to bypass the relay I mean to use the one there now or if I have to use another new relay and wire it proper using beaver gauge wire from battery to repay to starter with using like 12 gauge to send power to it from the button .
Anyway it's gonna work somehow tomorrow lol
Here one of the videos below I watched mostly for u to see the button that I have here not that this guy does a great job with his wires but it does work for him .

Thanks for the video! I thought about this after watching it, wondering if he means to hook it up like this?



I think you're right to be concerned about the wires - the ones that come with that kit look kinda thin. Maybe your plan to go with bigger wires and a different relay is the way to go. :silly:

Hi Tyler, this my first time using a fourm for anything and it's kinda cool. What you have drawn above you have the new with to the green w/black wire which comes alive on final turn of the key. There's only one neg wire and it has to go to ground.
Anyway, I spent 4 hours yesterday working at this and it's totally amazing and great for someone looking for a challenge. I tried everything and nothing. Removed tgepurplr start relay and placed pos and neg power to correct marked terminals and then I used ohms meter to check the other two terminals on the relay and I was shocked, it did not close using my bench power 12volt. Never seen that before ever. So went back and again tried every possible thing and nothing. I'm thinking there has to be something else inline to starter from relay that's stopping the power flow. I am finally stumped and had to walk away from my very first work g project ever. For 20 years I solved Evey issue but not this time. It's a puzzle that's either very simple or only Toyota knows what's happening haha
Anyway I removed everything g for now from truck and replanted my dash panels. If you can find this out somehow please let me know lol cheers man: )

Really? :huh: I guess I forgot to ask this earlier, but does this truck start normally? If so, then that relay has to be doing something... If it doesn't, then you may have found the problem.

Yeah, sometimes you gotta walk away for a bit before you get too frustrated. I went over the diagram again, and I still can't find any reason the push button shouldn't be working, assuming that the system worked beforehand. It's possible the diagram may be flat-out wrong! Or I looked up the wrong one? I'll recheck.

The relay is working great when starting with a key so it's not the relay. It's just sometimes I have to wiggle the gear shifter while the key is turned for it to start. So it's the switch in the transmission and I thought this back up button would work great when that happens. Button is working OK also, I applied 12v to the black and red and then texted the blue wires and works great 12volts there also with button pushed and gone when u release it. This one beats me: )

Ahhhhh OK, so there's some kind of neutral safety switch issue. It kinda makes sense the button is struggling, then, because we're ahead of the switch in this diagram.
