A nice touch is the subtle notch on the BU1 AC that lines up with the base each time.
FUJI ELECTRIC TR-ON TR13N 7-11 A OVERLOAD RELAY
What stands out about this relay is how the Audiopipe branding is clean and simple.
When a relay acts up, the Relay Bypass Switch Kit lets you move pastiring.
A nice touch is the Switch Harness Set, and it feels sturdy enough for repeated use.
I trust this automotive relay because the model handles high current without getting too hot or losing contact.
