So I hooked up all three wires. (Black, WHite and Grey) I see the harness plug on the TT brain. Now I can make individual plugs/wires, but have no idea where they go. I know the red on the TT is power, but the green and blue wires go where exactly?????

 

morning bump

 

check apexi.com or call them tell them what you r trying to do and they should be able to help. there very helpful good luck

 

Blue on the Apexi side should be accessory power. Green should be ignition.

 

cool thanks. So basically open up the steering column. Find the ignition harness, then splice red to red green to green and blue to blue right?

 

I would imagine these wires would be accessible from underneath the dash. Not positive, but they probably run from the steering column, under the dash, and into the center console (I am assuming that is where the EVO ECU is located).

Its generally pretty easy to tell which wire bundle is for the ignition key cylinder. They tend to be thicker guage wires than are used elsewhere (ie. 12 guage vs. 16 gauge). You can probably search the forum to find the exact location under the dash.
