I got a blitz dual turbo timer from a friend of mine and i have no idea how to install it. I've been looking but i can't seem to find any sites on installing it. The blitz website i found didn't help much at all. ???

 

I have two plugs. One with black, red, green, and blue wires. And one with purple, orange, and white wires. Then i have a black hose coming out of it too, that im guessing is the boost gauge. Anyone?

 

Here's what i found so far:
Red (12v): White
Green (ign1): Black/Yellow
Blue(?): ?
Black: ground
Purple: e-brake

My greddy turbo timer had the last wire (blue) going to the yellow(ign2) wire but from what i searched the blue wire goes to the acc which is a white/black wire. So which one do i use?
