Song Chuan Automotive Relay, 12VDC 30 A, Weatherproof Replace HELLA # GM 12193611 (Pack of 2)

Worked good for my boat when I needed to replace the relays.

Relay working good so far, was used to replace failed heater blower relay. Relay did not fit the GM mounting strap, had to used the provided mount strap and drill hole and screw to firewall.
