Resolved 2G A/T Plug Wire Color Help

Over the past few years, I'd like to think we've been of help to several fellow 'Tuners members, but now we need your help:

We had the auto trans on our '99 Spyder rebuilt using, among many new parts, a new solenoid harness and solenoids. One of the two, four-wire plugs that sit next to each other on the top of the trans was broken, so we put on a new plug by removing the old pins from the harness and back into a new plug.

We're concerned that the order of the wires might have gotten changed during the process.

Will someone please look at the color sequence on your 2G auto trans and tell us the correct color sequence?

Thank you so much for your help.
