Overview:

Clean up your wiring with an MSD Solid-State High Current Relay Block. This high current module takes the place of 4 standard relays and eliminates unsightly wiring. Four independent channels can be activated using either power or ground. Each channel is capable of handling up to 35 Amps of continuous current, providing up to 140 Amps of power.

Controls electric fans, water pumps, nitrous solenoids, auxiliary lighting and any other electrical accessories that would normally require a relay. LED status indicators ensure proper wiring and operation of each channel. Should a problem arise, the relay block has built-in automatic over-temp, short circuit, and overload protection, as well as a channel reset.

Worth it, I have 2
Style: All Season, Size: King
Soft, good material, I like the thickness. Does not feel cheap.You do have to put it in a dryer on really low to fluff it up. Check it after 20 minutes. Pull it out fluff it up and put it back in the dryer. Do not use hot heat. I also put it in a linen duvet.
