Review: Didn't work, malfunctioning - I'm giving only this 2 stars just because I got it fast, but unfortunately it didn't work. When it was put in place it wasn't delivering any voltage so my car didn't even cranked nor start. The worst part is since I live outsider the U.S (in the Dominican Republic) I can't returned it because it is more expensive send it back than what it actually worth.
Review: Chinese Product - Photo clearly has made in Germany on relay yet upon receipt the box says made in China and the relay is unmarked. Junk Chinese product.
