USDM vs JDM engine harness wiring colors

Working through my S6 jdm engine harness, and have had trouble finding pinouts. I have found s7 pinouts, but they are different. I have usdm harness pinouts, does anyone know if wiring colors are similar between the usdm and jdm s6 harnesses? I am removing a lot of unused connectors(single turbo) and trying to figure out which connector is which. Since the harness is laid out differently, I can't go by usdm connector locations to differentiate them.

I cant give any guarantees but i've been using the USDM wiring for my 1992 and everything I remember touching has lined up and made sense. From speakers to injectors.

It's mostly the same, small differences on the emission harness.
The engine harness isn't much anyway, battery cable, oil level, ignition, PS, oil level and pressure etc..

I’m not touching the lower harness, just the efi harness. I’ll pull out the usdm FSM later when I get home and do some comparisons with the connectors I already know
