DBW question 98 corvette donor?

I was working with my a friend today converting a 98 corvette harness over to stand alone.

We got to the drive by wire stuff and have some questions about wires.

There are five wire comming out of the TAC box on the wireharness side that I do not know what they are.
Dark Blue
Light Blue
Pink
Grey
Grey/Black

All of these wires went to the black board, not to sensors.
Any help would be appreciated.
Thank you.

Awsome info thank you, one final question on this PNK, how much current should I supply it, from the stand alone, or can it just go hot on ignition?

When I do a SA harness I normally use a fuse for each circuit and I put my amp meter in place of each fuse and measure the current, the circuit draws. I double the number and go to the next standard fuse size. If the circuit pulls 3.3 amps, I'd double it to 6.6 amps, but the next size fuse is 10 amps, so thats what I'd use. If you're use using the same circuit combinations as the factory, you can just duplicate the factory fuse chart. If you need more info, email me through the forum, but right now I'm on the Hot Rod Power Tour, and don't know how often, I'll be able to get internet service, s oit might take a day or two to get back to you. By the way a long time ago, I worked for a vehicle manufactor and that how we did there.
