I noticed the model listed is DEK-OE- 12DC/ 48DC/100.
5 Pack 40/30 AMP 12V DC Waterproof Relay Kit with Heavy-Duty Pigtail, 5-PIN SPDT
The model value is N/A, so you can match the relay by pin count and mounting style instead.
What stands out about this unit is the pin style relay that makes wiring less of a headache.
