Review on 🔌 5 Pack Bosch Style Waterproof Relay Kit: 12V 5-Pin [Harness Socket] [12 AWG Hot Wires] [SPDT] [30/40 Amp] Automotive & Marine Relays for Boats, Auto Fans & Cars by Adam Gray

Very well made and uses 12 AWG wires for input and output. 86) Yellow - Exit N/C (87a) Blue - Exit N/O (87) This is not the case. All five they sent me have the red wire going to pin 87, not pin 30. Pin 30 is powered by the blue wire. I emailed them and they said all five were probably hooked up incorrectly. Strange, but I understand there can be mistakes. They offered to fix the problem - I declined as it didn't make much of a difference to me. And I can report that they work as advertised for my application. See her installation in the lower left corner of the photo. Yes, I shrink wrapped all the wiring to match the rest of the wiring.
