Looms are typically custom made -- often by the MoTeC dealer or distributor in your country. Where are you located? On many of the harnesses I see (and have built in the US), you will find the following colors used:
Red - +12V power
Orange +5V
Purple +8V
Black or Brown 0V
Other than that, we typically see Green for CAN Lo, and Yellow for CAN Hi.
I usually create a spreadsheet for each harness and supply the customer with what colors were used. I know that MoTeC USA does the same thing with their standard harnesses.
