Hey guys I am bought the blitz dtt off a person in the forum and I was wondering if you guys can help me out with the wiring. He sent me the instructions but they were all in japanese.
From searching and reading threads about this and due to lost pics I found that the purple wire attaches to the ebrake. I also know that the vacuum hose to the right of the pic is for the boost gauge.
1. First of all I would like to know if he sent me the evo harness?
2. If so, can someone post pics on how it hooks up?
3. I'm assuming the two black wires to the left are for ground? Can someone verify this.

Thanks in advance guys

 

Here is the pic guys

 

Hopefully this pic is better.

 

he did not send you the harness.....

 

thanks
what about the other wires

 

I have the Blitz DTT-X. My instructions say the harness is optional. Here is what the instruction sheet says about wires:
Purple - ground or handbrake
Black - ground
Red - 12v constant
Blue - secondary ignition or accessory wire
Vaccum tube - vaccum/pressure source behind throttle body.

Is one of the wires purple? You may have to clean it to tell. Hope this helps.
RAW

 

Buy the harness... believe me.. it will make it 150% easier for you!

 

yes buy the harness, its alot easer, with it i got mine done in 30 min. get it.

 

Raw thanks for the wire scheme. Well, I actually went home to the valley (fresno) to visit my mom for the weekend. I need a boost gauge for the road trip back (late tonite) I might just tap into my wires. other options I am considering is buying a cheap-*** boost gauge from autozone or something. Its kinda hard to get things here in the central valley so I don't know what I am going to do. I'm considering taping into my wires.

RAW, yes one of the wires is purple.

Can someone else verify the wires?
I'm **** like that.

 

By the way what is the green wire for?

 

I decided I am going to just buy the harness. Do I stick the harness to this setup or do I take out the current harness and plug the evoIII harness directly to the first harness output.
