This is the short version. When I searched I found a lot of info for the VIII's but not the IX's. Alot of the info wasnt confirmed either.
Using the MT-6 HKS Harness is pretty much straight forward intall on the steering column. The grey wire from the TT is going to the parking brake Blue/Red wire.

The RPM signal and the Speed Signal wires from the timer are connected like so on the ECU

First is the RPM Signal Brown Wire from the TT goes in the brown/green wire on the ECU like Pic 1
This is the Middle Harness


Now the Speed wire Blue Wire from the TT goes to the black/yellow wire on the harness like pic 2
This is the first harness from left to right


last but not least a Thanks to Sam @ SRT for the TT and the Harness...

 

ive been looking for this edu with pics for such a long time, thanks

 

wow owulda been nice if i had this when i did mine. but i ended up never using any of the damn options anyways

 

the text and pictures are confusing. i can't tell what you're doing really. so you don't have to take half the dash off, or the glove box out? you can do it all from the steering column?

 

i'm really interested in this because i'll be installing one of these next week. thanks for the help

 

can you pass those links for the installation in the VIII or whay should I change from yours.

 

I will have to take pics of how i did this, but if you search for installtion on the 8's its the same thing, the only reason i changed this is because of the wiring on the ecu, its different from the 8 and 9's. The RPM Signal and the Speed signal wires are different. PM me if you need help.

 

just tried it. =/

 

thanks for the help. these pics help with the evo ix love the tt

 

Just did it....works great....

 

So these wires that you tapped are in the steering column or at the actual ecu and its harness?

 

Great write up, just did mine in a hour flat. Didnt even look at the HKS directions.

Dont use the wire connectors that come with, go to true value and get good ones.

 

I have a Greddy TT and only have the instructions to hook up the VSS wire to a Evo 8 ecu. I assume i would connect it to the black/yellow wire (pic 2), is that correct? I just want to make sure.

 

Edited;

I don't know why my wiring was not as simple as the HKS instruction manual or this guide.
I faced some problems like TT does not counting down/working properly, Tamrac/Gravel/Snow bulbs and the Anti-Lock continuously on (My car was running okay and without these stuff being on continuously)

PLEASE TAKE NOTE:
If your turbo timer DOES NOT COUNT DOWN after you turn off the ignition, do these;
CAREFULLY cut a lil piece of the plastic(which protect the wire) off the wire so that you can see the COPPER.
Then continue to follow what Sr20kidD says in this thread about the installation. You may do the same for all connections not just for the E-brake but also for RPM and Speed Sensor (My new HKS type 1 has these extra features)

Good thing;
Better flow of electricity in and out.
Better reading for the TT (I don't know why some people would ignore the extra functions or not using them)

Bad thing;
You have to spend more time to install the turbo timer.

Have fun.

*I'm not responsible for any damage and what-so-ever because of what I wrote here, just want to help out, minimizing the headache and pain from install the timer*

 

Good I was looking all over this forum for this write all the other ones explain how to do it on the IIIV but none of them explained it on the IX.

just out of curiosity when do you guys use the other functions? and how often?
