05 Tacoma anti-theft help?

I drive a 2.7L 2005 Tacoma. I am worried about the vehicle theft in my area, and I need to install a hidden ON/OFF switch so it can't be stolen as easily. The fuel pump relay seems like a good idea, but I haven't been able to find it. Is it a Circuit Open Relay? I need to drive my truck every day, so I'm worried about cutting wires and doing trial-and-error. If anyone can help me, I would appreciate it

 

disconnect the negative battery terminal

 

Get a Viper Alarm with GPS tracking !!

 

That’s a lot of work, but it works!

 

Sucks to be in that spot sorry.
You could pull some relays from fuse box?

I've been doing that, but a friend had his car stolen as they jammed wire bits into it. Car turned up later (totaled) and he could see the wire they got it running with. Apparently they had been watching him come/go to work every day and saw him in the fusebox, so they knew what to do. Disconnecting the battery is easy to replace, and wears out the terminal. There is a lot of vehicle theft in this area. If I can find either the fuel pump relay or the circuit open relay, I can add a secret switch under the seat.

I've been trying to find the fuel pump relay, but it seems like the Tacoma has something called a circuit open relay? It seems to be the same thing to me? I can't find either. Anybody know where either is? I don't want my truck to be the next one, I really like it...

 

Found this on another thread

 

That's a good link, it seems it is simply part of the fusebox itself. I'll look into that, thanks.

 

Thanks, I'll try the C/Open relay. My truck is a 2TR-FE engine, so apparently no fuel pump relay.

 

It’s a relay pulls out like fuse kinda.

 

I found the relay switch thing. It's the third of these light blue boxes in the bottom right when viewed from the driver side wheel area.

I took it out, and tested. Made a single piston fire and then it just turned over, so I'm sure it's the right one.

So I tested with a DC multimeter. All 4 prong spots are 0 power, both when sitting and with the key turned. Confusing...

Any ideas? I guess I can just stick wire bits to connect the relay to the socket, test what removing each of the 4 does, and see which wire I want to add the on/off to?

Should I do that and try measuring the amps? I'm not great with electricity, but I am good at wiring.

 

The pump relay is not going to be hot unless the truck is running. It will turn on for a second when the key is turned to "on" to prime the lines/rails, then it shuts off.

If you're looking to use a switch, make sure you are switching the ground on whatever circuit you tap into. You do not want to run voltage, particularly someone with a lot of amperage, to a switch. Always switch the ground if possible.

 

Stick shift?

If it's an automatic I'd much rather interrupt the starter circuit.

Mess with the fuel pump and you'd better make sure your wiring job is as good as the factory did it. Every wiring problem I've ever seen on a car has been from add-on stuff. You don't want the truck shutting off in traffic.

With an automatic you can do starter interrupt and put a key lock on the hood.

You could also check this out: http://www.ravelco.com/ they have a real good reputation and they'll install it for you.

 

ok, I'll google how to find the ground.

Manual here..

 

If it were me, I would cut the blue/black wire between the copn relay and the ECM and install a switch. This is going to be a very low current ground wire.

Do you live in Alaska OP?

 

Great stuff guys, thanks for the help! I'll look into this stuff and see what works. I'll do some research when I have time, new job starting so it might be a bit. Thanks again Tacoma bros, I plan on keeping mine for a long time, so doing this properly is a must for me. I'm surprised these kill switches aren't more popular. I'm adding mine as I stay over at my new gf's house pretty often, and the car theft in that area is very high. Sketchy neighborhood...

Yes, I live in AK. Perfect truck for a place like this. I damaged my rear suspension by hauling branches/food to some rescued moose (yes, really!) as the road up to the old facility was terrible and I needed a running start to make it up the hill. That was one month before Toyota upgraded my suspension for free due to the recall! I totally lucked out on that one, as the recall was 10 or so years after my truck was made, and within a month of my suspension feeling strange over bumps. I'd been carefully driving around with it as it wasn't too bad, and I was pricing out a repair when the letter showed up!

The only other issue my truck has is the fan settings - Off and high speed both work, but the middle settings rarely do anymore. A few years ago, the middle settings started to only sometimes work, and then rarely work, and now they almost never do anymore. Very strange problem, but not bad as off and hi are the important ones. If anybody has any idea, let me know.

Don't forget to spray the leaves and junk out of the front wheel wells guys! I do it once a year at least. I'm always surprised to see how much pine needle and leaf build up is there each year. It's why the wheel wells on many Tacoma trucks are rusting away, it decays which makes it acidic, and it holds the moisture in there. Just spray the junk out with a garden hose.

My truck was serviced by Toyota at 80K miles, and it's now at 130K with me changing the oil and air filter and greasing the fittings on the bottom. Anything important I need to check? I'm pretty new to working on cars/trucks as I've been under warranty and getting service until fairly recently. I'm great with motorcycle engines, so I do have some wrenching experience.

Thanks again for the info. I joined as it seems like a good forum, and I'll probably have more issues as my truck ages.

 

These are both natural Toyota occurrences.
Welcome to TW!
I have owned 3 Toyota's prior to this truck.
Bought the truck used, washed and polished it up, checked the wheel wells and yep!
Full of wet leaves and debris.
Just like my previous Toyotas where the wheel wells rusted out.

The fan speed relay ting is a plastic plug connection that burns up over frequent use.
This too happed on my previous cars but I didn't know back then what was wrong.
I knew I had a high speed blower and in FLA & GA that's all that matters!

There are threads on here re: that plug burning and replacement.

 

Cool, I'll look up that plastic plug fan thing in forum search. It will be nice to have medium fan settings on long drives and such.

My first vehicle was a 93 Tacoma, actually called a "pickup" before the Tacoma name. It came from Florida, and had the worst sunburn I've ever seen. We don't get that up here in AK! I had a lot of fun with it, and I sold it for the exact same price I paid for it. It's why I got another one.
