2006 XC90 - Transmission Shift Indicator Wiring Query

[Joncanland]

Hey everyone, new to the forum, had a great V40T4 a few years ago, and just bought an old but still decent condition XC90.

I'm doing some work on the old girl as she has been neglected for quite some time.

Discovered that the wiring had been disconnected from the Shift Indicator. (See pic).
I'd prefer to resolder this than buy another one. Can anyone help with which wire should go to which pin?

And any advice on particular things to dig into and/or preventative maintenance would be really helpful.

Many thanks.

Jon
