98 s90 stereo wiring diagrams don't match up

[codywansley]

I've looked everywhere for a diagram to put in a custom radio on my volvo, the ones I've found are all the same so I figure they must be legit, but when I went to look at the wires on my car...none of them matched!(well except for the red wire was there) but absolutely none of the wiring matched up to the diagram. this is the diagram i looked at in case yall want to know
so far this has been the most problematic car when it comes to finding out information and it's getting on my nerves.

Did you go with a wiring harness? Here is Amazons: https://www.amazon.com/Stereo-Harness-Vo ... ng+harness

I know VOlvo has one for this purpose. I would probably go with theirs. I plan to put a nav unit in mine next year.
