How to: 4th gen '05 Remote Start Install

Here is the remote start and immobilizer bypass that I used in this install:

Avital 4113
The remote start is a basic single button remote model. Priced around $50 it's perfect for our 4R's since our OEM key FOB already controls lock/unlock functions, as well as the rear window.


Xpresskit XK05
The immobilizer bypass doesn't require a key, is very small, and can be re-flashed (if you purchase the bootloader) It's priced around $30.


First remove the lower access panel by removing the 2 10mm bolts, then removing the 4 items attached to it (blue circle). Set the piece aside.

Then remove the metal guard with 2 more 10mm bolts


These are the connections you'll be making to the remote start (red dashes)



We'll start with the large heavy gauge harness. It needs to be connected to the vehicles main ignition switch harness.

Locate the main ignition switch harness connected to the ignition switch. It will have large gauge wires connected to it. Unplug it and cut away the tape so you will have enough room to separate the wires.


This is the wire color and location of the connections to be made:



Start by stripping a little insulation away, just enough to be able to test the wire. TEST EVERYTHING! The info here is solid (I know because...well....I just did the install!) but you can never be to sure.

Once you know you have the correct wire, you need to isolate it from the rest so you can connect to it. I first make two cuts about 1/2" - 3/4" apart (red lines) then a cut straight down the middle. Be sure not to cut the actual copper wire, you only want to be cutting insulation.


Once the wire is exposed, be sure not to short it to any other wire or metal part on the vehicle. You could disconnect the battery, but then of course you wouldn't be able to test the wires you're connecting to. As long as you connect one wire at a time, you'll be fine.


Next grab the harness from the remote start that you'll be working with (the heavy gauge harness in this case) and shorten the appropriate wire to the desired length. This will keep your install cleaner by reducing the amount of wire you'll have to tuck away later.


Now lay the wires (the remote start wire, and the vehicle wire you're connecting to) parallel to each other. Wrap the wires around each other and solder with a fairly large soldering iron. Don't get crazy with the solder. There shouldn't be a big blob, just enough to penetrate both wires.



While the joint is still warm (not super hot) wrap the exposed connection with electrical tape. Be sure to wrap the tape tight, and cover a good 1/2" on both sides of the solder joint. Take your time and keep your fingers off the tape as much as possible. It should look something like this:



So from now on whenever I mention something like 'Connect to this wire,' The above procedure is what I mean.

So go ahead and connect each wire of the remote starts heavy gauge harness to the vehicles ignition switch harness. They are:

- 12V battery
- 2nd ignition
- 12v battery
- accessory
- starter
- primary ignition

After that you only have 5 more connection to make from the remote start to the vehicle. 3 are in the 9-pin H1 harness, 2 are in the 5-pin H3 harness. The order in which you connect wires is irrelevant.

Next is the Horn. It's the lower left connector just above the gas pedal. There's 2 green/red wires, your horn is the one on the left (red circle). Connect the Horn wire to it.



Next are your grounds. There are only 2 ground connections. They are

- Ground in H1 harness
- Neutral safety switch in H3 harness

Both connection must be at ground in order for the remote start to activate. Because our vehicles already incorporate a neutral safety kill circuit (which means the vehicle cannot turn over in any gear other than neutral and park) simply ground this connection. So even if you attempt to remote start the vehicle while it's in gear, it simply won't turn over.

I removed the lower plastic steering column cover to access a bolt to use as my ground. You have to turn the steering while in both direction in order to remove the screws that will allow you to remove it.



Then I made my ground connections to a 10 mm bolt. Test your connection to make sure it's a solid ground of course.



Parking lights and brake. The parking lights are the visual indicator that tells you if your vehicle detected the remote start signal. You can also connect to your headlights or hazards if you wanted. REMEMBER TO SET THE PARKING LIGHT JUMPER TO POSITIVE, NOT NEGATIVE! The brake tells the remote start to kill it's power to the vehicle. Once you're in your car and ready to drive, it allows the vehicle to run under it's own power. It also prevents someone from stealing it. If the brake is depressed without the key in the ignition (someone is trying to steal your vehicle) power is killed and the vehicle shuts off immediately.

Both of these connection are made at the fuse panel in the far left connector.





And that's it for the remote start! Leave it unplugged for now of course.

Onto the XK05 immobilizer bypass. Only 3 connection here. From the XK05 they are:

- Keysense
- RX output
- TX output

It's wired like this:



Unplug the small 7-pin connector from the vehicles ignition switch. This is where you'll connect the violet RX wire and the orange TX wires. As you see in the picture above they connect like this:

Violet --> pin 4 (it doesn't tell you but the wire color is pink/green)
Orange --> pin 5 (wire color is green/red)

WARNING!! We're connecting to PINS 4 and 5, NOT the 4th and 5th wires!! If you face the connector straight at you you'll notice that PIN 3 DOES NOT HAVE A WIRE ATTACHED TO IT. IT'S EMPTY. Remember to factor that in when connecting to these wires. Make these connections.

One more. Keysense. This wire is tricky because the pin out tells you it's green/yellow (and it is) however it comes off the ignition switch as a black wire. It switches to green/yellow after is passes through a blue connector as seen here:



So if you separate the blue connectors and look straight at the side with the green/yellow wire, this is the pin you're looking for:





And that's it!

You're probably wondering why we didn't connect things like GWR (ground when running), Tach, or power the the XK05. This is because WE'RE USING VIRTUAL TACH AND D2D. I'll explain.

Virtual tach doesn't require a dedicated tachometer input to the remote start. It uses the systems operating voltage to detect when the vehicle is running and then stop cranking the engine. Once the remote start sees that the input voltage climbs from aprox 12v to aprox 14V, it knows that the vehicle is running because the alternator is spinning causing the increase in voltage. Once it detects this rise in voltage, it stops cranking the engine. Less wiring is good.

D2D (Data to Data) This is the 4 pin connection between the remote start and bypass. It supplies power, ground, and data. This connection allows us to not need GWR, power, ground, or data to be wired to the remote start and vehicle. Simply connect the 4 pin harness between the 2 and you're done!

Now we must program the XK05 immobilizer bypass. It is very simple. Connect all of your wiring harnesses to both the remote start and bypass and follow these instructions:



Last thing to do is to program your remote start remotes:


Now press your remote start button just once briefly (don't hold it) and the vehicle will fire right up and automatically learn it's virtual tach setting.

Now just clean up your wiring, secure both modules, and enjoy!

Forgot about the antenna. I'm sure I'll add a few things later too.

Remove the handle and a-pillar. You'll see there's a convenient pre-existing space to rout your antenna wire.


Tuck it into the headliner (no need to remove it) and run the antenna down into the middle of the windshield. Position it somewhere in the area that's blocked by the rear view mirror.

 
nice write up.


what is the range on that unit?
ive got an inexpensive RS on my 85, but the range is terrible.
 
Back in the day, I was an installer and here's a helpful hint.

For splicing into factoring wiring, you can use the knife method shown above but its not easy as it may look, especially for wires tucked way up in under the dash or other hard to reach area's. Its also really easy to cut through the wire with that method. This tool makes stripping wires in the middle (especially hard to reach wires) 100x easier...

Don't think that the vehicle lift in your garage went unnoticed....you suck...but that's only because I'm jealous.
 
I dont mean to derail this thread, but are there any plug N play kits out there?

was it offered OEM?

id rather not be splicing into any wires if at all possible.
 
i might be extraordinarily dense here, but i cant quite work out which wire goes to which on the ignition harness. any chance you can enlighten me?

Good question......You would assume Toyota of all companies would have been way ahead of other on something like this. Anyone? I'm still fairly new to the T4R community.
 
Minor update: I added the programming switch, and kill switch that comes in the kit. I kept them both accessible near the fuse panel.

The button is used to scroll through programming menus and change default options. The switch is used to lift the neutral safety input from it's ground. Therefore the remote start is disabled when the switch is off.


 
Unfortunately I had a remote start related no start problem happen in the last few days. Why does this stuff only happen with it's 7 degrees??

Here's the email I sent to XpressKit. I'll let you know if they jerk me around.

I purchased an XK05 immobilizer bypass in late February last year to be used in conjunction with an Avital 4113 remote start on my 2005 Toyota 4runner. Here is the install thread I created:

http://www.toyota-4runner.org/4th-gen-t4rs/163563-how-4th-gen-05-remote-start-install.html

Everything has been working perfectly until two days ago, my vehicle failed to remote start. It cranked 3 separate times but wouldn't start. Then I tried with the key and it started right away. I then remote started a few more times over the course of a few days without issue. Today however, the vehicle would not start under any condition.

I isolated the issue to the XK05 after I noticed my door chime ringing without a key in the ignition and the anti-theft light flashing on my dash. Essentially the KX05 is grounding Keysense (causing the door chime) but not actually bypassing the vehicles anti-theft/immobilizer.

I disconnected the XK05 and the vehicle started right up! Since the KX05 can not be reprogrammed, could you please send a replacement? Thank you.

While your at it, I would recommend moving your grounds to the actual body. I usually place my grounds in the kick panel area on the body itself. Be sure to remove all paint/primer first.

I have an Avital 4100 and XK05 bypass in my 4th gen that I installed back in 08.
 
Just curious if the vehicle remains locked, a lot of vehicles were stolen this week as the temps have dropped into the 30's and vehicles were not locked up.
