i had harness problem before and i was very frustrated.
i even tried hardwire the ig wires, but failed.
so i order new one (tt is apexi, but ordered HKS harness which is same thing)
the one that apexi made was defect.
i told my dealer and apexi-usa about bad harness.
but they all said the product is normal. (the 12v power line clip is mislocated)
so as soon as i received the HKS harness, i looked at the pins.
yes!!! the red wire goes into where it suppose to.
so i installed the harness. i had pre-cut O2 voltage, ground, and parking brake lines from previous apexi harness installation.
so everything went well, except the steering cover won't go in because of fat wire harness. i relocated all the wires so that cover goes in without touching wires.
now, i am so happy~~~ i see A/F ratio, voltage, and O2 voltage in digital.
and found out engine runs lean below 3000rpm, and rich above 3000.
now, time for ecu flash???

anyway, my point is that if your apexi harness doesn't work somehow, return the item for refund. there are defects like mine. don't do crazy things like me and end up ordering the harness again.

Did you get the auto-timer function to work? I havent heard of any evo owners that have...

 

The auto-timer function works for me just fine

 

Great, well I have checked my setup a hundred times and it doesnt work on my end.

 

lol.
good for you

 

auto function? i don't even care.
i always set it for more than 2minutes (3 minutes right now).
i don't mind waisting gas for 2-3minutes of cooling down and burning oils.

 

I had apexi also. Think you're going to like it.

 

I really like my Apexi TT! I love how tiny it is, so you don't even notice it. I can't get the auto timer to work either, nor can I get the A/F ratio function to work either. Oh well, doesn't bother me too much.

 

My autotimer works fine. You do have to tap into the O2 wiring, though.

 

I have the O2 sensor wire tapped, but i always get a blinking red light on the TT whenever I try to view my A/F ratios. Not sure what the deal is.

 

Mine only blinks when I first start the car -- after that the TT displays whatever I need.
