Works with a little effort
I bought this to install a new head unit in my 1998 Saturn SC2. It arrived on time and all the wires came pre-stripped at the end which made it easy to connect to the adapter for the radio. My only issue with this was that the wires did not match up with the harness in my car when I went to plug it in, so I had to take a bunch out of the plug and put them in the right order. It was not a difficult process, and it could be achieved with a little help from a paper clip and an extra set of hands (my dad helped me out), but for some reason I was expecting them to already all be in the right order. However, this was my first time working with car electronics of any kind, so I really didn't know what to expect going in. Having said that, even with that setback it still was not difficult to use and now that everything is straightened out it works great. No major complaints. Just be prepared to adjust some wires. A quick search on youtube for removing wires from a wiring harness was all I needed to correct the problem I faced.

Does not fit 1990 G20 Van
Definitely does not fit a 1990 Chevrolet G20 conversion van. Ended up buying a different harness somewhere else, but Amazon said it would fit and it does not
