1G Road surge shift box install on 3 plug TCU

[NeMiZiS]

My road surge shift box came with instal instructions, but they are for a 2 plug TCU.
Does any one have the instructions for install on a 3 plug TCU?
Basically I just need to know what wire to use for 12 volt power and what wire for ground?
Can the shift box be grounded to chassis instead of finding the ground on the TCU plug?
I have the yellow with a blue stripe and orange and they are hooked up to the box according to the directions.
But I don't have a solid black (ground) or a blue with black stripe (12 volt power)
Thanks.

This is how I ended up hooking it up haven't had a chance to drive it yet...

TCU side:
brown to orange/white to yellow with blue stripe
red to blue with black stripe

Harness side:
yellow to yellow with blue stripe/green to orange

I have the ground going to the chassis since I couldn't find a ground through the TCU.
