## Questions & Answers

**Q: Will this handle 12v on both sides of the relay?**
A: Yes, it will. And up to 20 amps on the load side as it says.

**Q: Does this fix the problem off the Mercedes engine fan going supersonic and not stopping?**
A: Not an answer to your question, but I am having the same problem with my 2007 mercedes CLS550 engine/radiator cooling fan running at super high speed constantly.   If anyone knows if this will fix the problem, please let us know. Thanks.

**Q: Can this be used to replace oe hella 4ra 931 716-00?**
A: Based on what I see, this crosses to the MB # 0025421119.  Info online shows this as a 4 pin Micro ISO.  Which crosses to the following IAM version.  See red part numbers.  Note the IAM version does not have the ears on the side of the cover.

**Q: Will this switch with the coil wired in either direction? Does it matter which way the coil is wired?**
A: There is no polarity on the coil.  Either way works.
