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. It also has the capability of Pulse Width Modulation (PWM). With a PWM input, you can control the output at a rate of 15 hertz and a duty cycle of 50-90%. 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. The solid-state high current relay can easily be mounted using the supplied hardware and mounting tabs that can be rotated 90° to accommodate various mounting locations. It's compact and clean design will make your wiring project a breeze.

Fit and comfort
Size: 12, Color: Ch British Tan/Ivory
These have to rate as equal to any shoes I've ever owned. I know everyone's foot is shaped differently but when I slipped my feet into these I was immediately sure I had made the correct choice. Sizing is true. You note, I'm sure, that these are slip-on shoes. My experience with slip-ons has been mixed as sometimes the heel tends to slip due to the maker leaving room for the slip-on function to take place. When I got these I discovered that the opening for my feet was so tight I needed to shoe-horn them in and it wasn't particularly easy. The heel counter was "high and tight" but once I got my feet in the shoes it was heaven. Then, after a couple of days wearing them I can now slip my feet into these slip-ons with ease and the shoes grip my feet like a lace-up shoe can do. I have one other pair of Cole Haans in the same size 12. They are also a wonderful fit for me. I highly recommend.

Great shoes true to size
Size: 11, Color: Ivory/Microchip/Ivory, Size: 11, Color: Ivory/Microchip/Ivory
Great shoes, came with box. Brand new, true to size 11 US ! :) in my country they cost 270 USD so, really nice and very comfortable shoe considering i have plantar fasciitis. 3 month update: They get wrinkles pretty fast in just a few weeks due to the material, it’s not noticeable to others at all, but it’s worth keeping this in mind when buying this particular model.
