It's also the wrong relay. The factory documentation is wrong and lists a 4 pin relay, when it should list a 6 pin relay. It's also the same relay used for the A/C system. Here's the correct part number that is not nearly as cheap:944.615.113.01.
There are a few posts on here about the relays being switched on the documentation

I just replaced my relay and I can tell you that it is a 6 pin relay. The four pin relay listed will only allow one fan to run, not both.
