Dell Mih61r Mb Front Panel Pinout ((exclusive)) Review
Search eBay or Amazon for "Dell front panel adapter cable" or "Dell proprietary to standard header" . These cables come with a 10-pin female plug that matches the MIH61R on one end, and individual standard 2-pin male headers on the other. This is plug-and-play and costs around $5–$10.
: Unlike LEDs, the power switch (Pins 5 and 6) is not polarity-sensitive; it simply bridges the two pins to boot the system. dell mih61r mb front panel pinout
