First go here:
http://www.volvowiringdiagrams.com/?dir=volvo/850%20Wiring%20Diagrams
Download the one for your year 850.
The 1995 is TP3907202
It's a PDF file and essential for DIY troubleshooting.
see the index and it will send you to page 82 for tail lights
This manual is the same as the older Volvo green books that are so useful.
Spend time with this manual, the wire colors and other details are
explained in the front, and then item locations and a component index are in the back. So you need to go back and forth from page 82 to page 200-203
to identify stuff on the schematic.
your LEDs will be polarity sensitive, check 'em before soldering.
Post back if you get stuck.
