Default HKS TT install...FINAL VERDICT!

Okay, here goes...

I know this thread has been on the list for like...forever, but NOBODY has ONE PROVEN method that the install works with the factory "upgraded security" package, and have all it's various functions work, eg. starter kill, and NOT have the alarm arm itself after the engine shuts off.

I am looking for a way to make EVERYTHING function as if NO TT was ever installed...except for the TT counting down, and engine running that is. This means: key out, TT counting down, door closed, press arm button, alarm arms (NOT valet mode, and lights blink, etc.), starter kill enabled, all alarm functions operational. After TT finishes, car shuts off, and all alarm functions STILL operational, as if nothing has changed.

Three methods has been proposed, and I'm just looking for the ONE correct one.

BlueRidgeRS's method, anyone proven that the above scenario works?

tdxflex's method, same thing, anyone?

buymeasti's method, I'm still discussing that with him as I'm posting this, and thus far I know I got ONE wrong wire, but fail to understand why that wire is needed to be spliced. Right now, I cannot arm my alarm, it chirps 3 times, locks the doors, but alarm not armed (open doors manually, and alarm does NOT go off).

I do think the problem is in the GREY WIRE, which is what me and buymeasti has discussed, but I wonder what EXACTLY the grey wire does?

Anybody out there that can help enlighten me, I truly appreciate it. Thanks goes out to buymeasti as well, for his help and prompt responses, even though I STILL can't get everything to work, THANKS man!

So all of you Subaru specialists out there, let's put this issue to rest once and for all! What's the ONE method?!

After you find the correct method like I did......you are going to have to turn down the sensitivity on the alarm so it doesnt go off.

The adjuster thingy is on that box next to the Ebrake

Does this mean you figured it out? So, what's your method? That is if you don't mind sharing that information with the list, I for one am dying to find out!

i just want to add that a lot of people are confused about wiring the turbo timers because i guess the blitz has some of the same colors as the hks? but they're using the hks harness? there are too many different people trying different things and then generalize and think all the turbo timers are the same, use the same color scheme, etc - but they are connected differently. it's almost like taking a vishnu unichip map and loading it on your turboxs unichip because they're both unichips so everyone thinks is safe to assume they're essentially both the same thing. you have to take a multimeter yourself and test out the voltages and do testing. mine works on my car, and i don't know what everyone else is doing but everyone can confirm that cutting the green/black wire in the keyless module, and cutting the grey wire under the armrest will work with exception of the starter kill. everyone needs to get that working first, then you optimize your logic.

what did you change to make the alarm able to arm itself with the car running, it's either in the green/black wire or the grey wire. the control unit that the green/black wire goes to even says on it keyless entry, so i assumed it was the grey wire. before making any modifications, the grey wire was connected and the starter kill worked. when people were first getting their turbo timers to work with the car on, people were cutting the grey wire alone but then found out the starter kill didn't work anymore. i went through all of the steps below assuming the problem was with the grey wire and everything works. if it didn't work, i start over and work on the green/black wire. i modified the grey wire - i'll try to break this down in the most general terms.

when does the starter kill work? when the car is off. so modify the connection for the condition when the car shuts off. what signal wire distinguishes when the car is on or off? the ignition wire under the key cylinder. the ignition is 12V when the car is on, and goes to 0V when the car shuts off. if you can't figure out which wire follows these characteristics with a multimeter, then you shouldn't be wiring your turbo timer on your own. now figure out how the relay works.


now just use the ignition wire to control when the grey wire is connected and disconnected. you need the grey wires connected when the car is off. again, if you can't figure out how the relay works from the two links i posted above, then you should not be doing this on your own.

i have an HKS type 1 turbo timer, with both my speed and rpm wires spliced into my ECU, and my starter kill working. I can view my peak/hold values for speed, use my rpm shift light, display voltage, do 1/4 mile times, i forgot everything else it does but they all work on mine.

What STR8OUT said about the sensitivity will most likely be needed because the alarm will be on when it's counting down and the engine running will be like someone rocking the car, and if you have STi engine and tranny mounts the extra vibrations will surely set it off.

if people want to disagree with me on this one, or found a different way to do it then that's fine, but everything is working for me.

Swank Monkey's method works.

Dark green wire is used to sense if the ignition is on. Grey wire is for starter kill. Run a seperate wire from accessory power to each of these. This way the alarm functions normally, the starter kill works and you can't arm the alarm when the car is running, but it WILL arm when the TT is timing down!!

IIRC the stock security system cuts fuel pump power so that cannot be left in place.

But this is how mine acts. It will arm, if I leave the A/C on when the compressor switches on it will set the motion sensor off. i haven't adjusted it down yet. but mine seems to do everything you want yours to to.

I had to cut the wire from the alarm to the fuel pump cut relay and the wire which tells the alarm the car is turned on.

I can maybe check the wiring diagram (real subaru dealer service manual) I have at home again and post which wires these are.

why couldnt you just put a relay in the wire that powers the shock sensor so that it is ignition controlled. so when the ignition is on the relay would be in the off position(reverse polarity) and the sensor would recieve no power. it cant be that hard
