Review on Low Profile Assorted Circuit by KOLACEN Automotive by Craig Mcdonald

Works well, no problems. The quality is good, nothing was broken upon receipt. Powered an electrical product in the car by plugging that product into an open socket in my fuse box. Just remember a few things: 1) If you have an unused terminal in your fuse box, make sure you plug the fuse into the bottom terminal of the fuse holder in this additional diagram, then plug the fuse into the top terminal , which will be for your circuit. The product will not work if the bottom port is empty and the fuse is only in the top port. Both must be activated. 2) Always install a higher rated fuse in the bottom terminal and a fuse that is one amp or less than one amp in the top terminal (I suggest using a lower rated fuse for the top terminal). The upper fuse must not have a larger current than the lower fuse. Determine the number of fuses required/recommended for your circuit and insert them into the top connector. Insert more below. For example, the bottom might be 15 amps, the top 10 amps. I used 7.5 amps on the bottom and 5 amps on the top for a switch that doesn't require many amps. battery) and which is the "OUTPUT" (which goes to your charge/product). If you know which side is "IN" (use a multimeter), that's the side where the metal pin is on the FLAT side of this piggyback design. The flat side of this product should always be on the side where your 12V power supply (IN) enters the fuse port.
