Tldr: One of these kind of works and the other one should work but I have not tested it. I'm selling both of them as is. Hence the low price.

One of these I pulled for my van a while ago. I don't remember which one of the two is the one I pulled. It is bad. Everything worked fine except for the charging output would never go into second stage of charging so I decided to change out the computer and the replacement I bought worked. At the time I bought two replacements and figured one of the two would work for my car and the first one I bought worked. So the second one is just a resale of what i bought.
