Help with Greddy turbo timer install

[Slow06WRX]

I'm tring to install my greddy turbo timer and it says to hook the red up to 12v, greed to ON, and blue to ACC. i found my ignition harness but don't have the direct plug in harness so i'm going to just wire it in. i see 5 wires coming off the back of where you put you key but only 4 wires make it to the plug under the steering wheel. those four wires are black with blue stripe. black with yellow stripe. black with white stripe. and all black. can someone please tell me which wire is which and which wires i need to put what to? i'm sort of a noob when it comes to this stuff and without a wiring diagram i'm screwed. thanks for any help. btw the wire that doesn't make it down to the plug is black with green stripe. i assume this wire is the Starter Signal but i'm not 100%.

Im not trying to be an asshole im just saying thats what they are for, I had one when I put my timer in and it made the job 10 times easier for only about $10, its worth it.

the timer is not even needed unless you have changed to a turbo that isnt water cooled. if you are on the stock turbo you are wasting your time

+1. Yeah just sell it and buy a downpipe or uppipe.

sigh...thanks for the info, i went to the dealership and had a guy print me out the wiring schematic for the ignition switch. it was easy to hook up and it's working great now. seems like every forum i try and post on i get flamed/shutdown/told what i should buy. i understand it's not needed but if it adds just a little bit more life on my turbo it's worth it to me. plus i think it's a cool thing to have.
