1998 S90 PNP wiring - wires pulled out of the harness

I was replacing my PNP switch, everything was going well until I tried to unplug the old one. The wires pulled out of the harness plug side. Now I cant find a diagram with the wire colors and location to put it back together. Im dead in the water as they say. can anyone help me?

If anyone has a picture of the plug or knows the pin numbers i believe they are:
1234
5678

I have found a wire diagram but not the pin number locations. I plan on spicing the wires to the PNP switch once i have the correct pin numbers or picture.

If the plug has 8 positions and only 5 wires try this:
Plug B4
1 Green
2 Green/orange
3 Yellow/white
4 Pink
5 Brown/black
6 not used
7 not used
8 not used

If this isn't correct let me know and I look again. This info is from S/V 90 Greenbook on wiring diagrams.

Plug B5 is the other posibility
1 Blue/yellow
2 Brown/pink
3 Blue
4 Blue/pink
5 Blue/green
6 Brown/white
7 Green/brown
8 Green/white

it is the B5 as there are 8 pins and 8 wires. with the positions being
1234
5678
this seems to work. the only issue I have is a check engine light but my 2 OBDII readers don't find a code. must be a trans code from me guessing at wire locations.

thank you.

If you want to PM me your phone number I'll text you some pics of the connector. I had to swap an engine that also required transmission removal. A couple of the wires did pull from the connector.

Went to PULL A PART and snipped off the 3 connectors at the transmission with pig tails if I need to address any problem on mine. So far it's OK so I have this small wiring harness with the 3 connectors still connected. If you PM list the color of the PNP switch wires. The harness I have is all 3 connectors at the transmission.

I've taken pics and texted to you. Let me know if it was the correct connector. Thanks Dave
