hks type 1 turbo timer install help

[boosted brit]

I bought the turbo timer a few days ago and the guy i bought it off said its for a dsm, so i didn't even think twice about a wiring harness, my interior is already dismantled for some other stuff i have been doing, and I would have really liked to install this to save ripping it apart again, I'm ok with cutting and splicing wires if it means i can get it done today, does anyone have a diagram that i can work with or a walk through? I'm already aware of the speed/rpm sensors etc it just the 3 pin(red ,green and blue/red) i need directions for.
thanks for the help in advance.
